Lignum Vitae Spyderco Stretch w/ ti liners.

This is one I did a long time ago and should have loaded up here on my blog a long time ago as well. I am really surprised this Spyderco Stretch was not added because the lignum vitae handle scales I did for it and the ti liners for a complete rebuild of the body really added a lot of class to this folder. Its probably one of the better Spyderco models that left my shop after completing the job. The gentle feathering pattern of this particular slab of wood I had when this was done really came out so nice it surprised everyone. With age the handles have darkened some with exposure to sunlight which is a typical reaction for this wood once it is aged.

It is normally the case that when you add lignum to a folder the knife gains some weight but since this one was all stainless before it really equaled out quite well in the end. As is shown here the knife was not equipped with a pocket clip. The owner, the Deacon on blade forums and the Spyderco forums didn't want one and does not use one at all. The R2 model I did that is posted in another thread in older posts from 09 below belongs to the the Deacon and the Atlantic Salt in stabalized birds eye maple scales with titanium liners in a 2008 post belongs to him as well.

Low Rider Pocket Clips For Folding Knives

Someone asked me if I could do a CASE knife. Unfortunately the only one I could find a picture of is now posted. A Case Trapper in yellow delrin handles with one of my low riders installed on it at the owners request. Just for you S.

Do you own a folding knife that does not have a pocket clip and you wish it did?

Maybe you own a folding knife with a pocket clip you've damaged?

Maybe its a folder you own but equipped with a pocket clip you just don't care for because of various reasons, the most common being that it advertises to everyone near you that you have a big ole knife on your person?

Fortunately I can solve that problem in a lot of cases. Thats right! In many cases I can make a custom pocket clip to suit your needs using the existing holes already drilled and threaded into your folder body from when it was made. In other cases I can drill and thread new holes and mount a new pocket clip if you want a different mode of carry. Some knives come with the pocket clip orientation set up for tip down carry from the factory and if you happen to like tip up carry and your knife didn't come that way it can often times be changed in this way also. However, it will void the warranty to do it this way should you choose to go this route where I have to drill new holes.

Seen here you can see two different sets of photos. In each set is three photos and two different production factory knives are shown. The first from the bottom up is a Spyderco Para-Military. The second is a Spyderco Persistence folder. If you scroll down to what would be the last picture for this post as you go down you will I know its probably confusing but this is actually the first picture even though you have to scroll down to get to it. The first picture of each set is what the knife was like from the factory. In other words its the 'before shot' when the knife first arrived here for a new clip.

You can see the factory look in that first picture of each of the two sets showing the way the pocket clip allows the knife to clip to your pocket from the factory but leaves it stuck up so its up out of the pocket, sometimes to the point its very obvious or you can opt for one of my pocket clips and hide it better by burying it in the pocket so all anyone around you sees is a pocket clip and not necessarily even well enough to identify what the clip is attached to. Some customers even opt for a color anodizing job like that khaki clip shown so the pocket clip blends with slacks at work. I've done countless blue jean blue and khaki pocket clips for folks as well as bead blasted ones. Since my clips are all made of 6Al-4V titanium alloy they are both light weight and strong and come with incredible durability and toughness as well as the inherant 'memory' that titanium is famous for.

For what its worth, besides viewing here you can view other pocket clips and my work posted by customers as well as myself by visiting either one of my two forums at the following links pasted below. You may have to register as a member to view the pictures or get on my forum, I'm not really sure. Thats a simple matter if so though and certainly worth it to view more if this interests you. Please list the referal from me when you do so if you register. Once there you can also see my other sticky posts titled "Read this if you need to mail me work" and in that thread or my "Low Rider Clip and Mailing instruction" sticky threads you can find my work order form needed for every job I do.

Once on my forum simply find the post your looking for or one with a title that interests you and click on it with your mouse to enter that thread. Feel free to ask questions or post pictures or heck start new threads of your own for any new topic you wish to discuss. If there for a clip then follow the simple instructions there in one of my sticky threads to fill out and print my form using the very easy pdf file at the link I've provided and once done use the address on the form to mail with your folder if I need it or to email the form to me if I don't need the folder from you to fit the clip. Turn around time is very quick on smaller jobs like these. Usually well within 24 hours from the day I get the knife. If its a more popular model you own that I get requests for more frequently I often times will not need your knife to make the clip since I already have the template to make it. Also if you are overseas outside the USA or have other questions contact me first and we can discuss the possibilities for your particular folding knife. Check back often on my forums and here as work gets added periodically. Thanks for stopping by. STR

Mini Titanium Prybars

Seen here are some .090 thickness 6Al-4V grade 5 titanium prybars I started making a few years ago. These started out as a smart way to use up some scrap left over end cuts of titanium sheets I had from folding knifemaking but that were too small to use for folders. It didn't take me long to realize there was a market for them albeit a small one. I don't make that many these days like I did when I first started offering them but when I do make a batch they don't last long usually. I'm down to six remaining from this batch at this writing, most of which sold before I even got the pictures loaded everywhere I wanted to put them. Go figure.

Anyway, these are great stocking stuffers for Christmas and make great gifts for other times. They run $20 plus shipping for first class mail. If you prefer Priority mail well thats possible just add $4.95, but they are usually just as fast getting there first class and its cheaper. International shipping is a case by case basis and you need to contact me first to work out how that will be done and the cost.

These are available in a variety of colors as you can see and each one is slightly different as I do still do these up from base raw materials all by hand from scratch. I wrap them either in para cord or some other decorative nylon cord wrap which you can pick for yours should you buy one. This cord helps to aid grip and looks, as well as, allow one to carry them on key rings.

I have been told my pry bar is quite handy. They have been popular with a niche group most often popular with folks working in 'non knife' office environments or where "sheeple" friendly attire is needed like a public job where they are seen a lot. Also, some people like having a tool on them besides their knife and don't particularly want to use their knife for jobs that will ding the edge all up or break the tip so this little tool here fits the bill and can actually open boxes and pop tape to separate it from the roll or lift a tab, as well as, pry staples and other things doing the stuff folks want done. I've also sold some of these prybars to police officers that use them as PI (private investigation) probes for evidence gathering and investigation work at crime scenes to dig around in places they don't necessarily want to touch with their fingers. Apparently titanium is preferred because it is an inert metal and will not contaminate the crime scene. The way I make these they are actually equipped with a flat head screwdriver on one end and a pry bar on the other. Many folks that carry Emerson folding knives like these for the flat head screwdriver; as they can use their pry bar to adjust their pivot screw tension. If you are familiar with Emerson knives you are surely aware that the pivot tends to loosen over time so these can be quite handy to have around on your key ring if you happen to carry an Emerson folding knife.

These pry bars, while not what I'd call extreme heavy duty are still plenty thick titanium so they do hold up quite well and you can actually get rough with them. Believe me people have done so and then told me about it. I have customers that use them from all over the world at this point and while they are certainly not what I'd call a hot seller they do seem to serve a purpose for some so if one interests you here let me know. If you like the idea but wanted a heavier one or one longer maybe, well, I may have some thicker scraps of titanium in the shop from folding knife making and other things I'm into so just ask. Again, I will have some of these for the holidays since many office parties and get togethers require gifts under $25 and these fit the bill. I'm easy to reach by email and that seems to work best for me.

Thanks for looking.

Custom Anodizing For A BenchMade Mini Skirmish

I had thought that for this blogger I'd just post the bigger more challenging jobs I do for folks but this turned out so well and really turned the folder around image wise so much that I thought it was worth showing here. Its not something I've posted here before but one of many other smaller jobs I do still offer that I have reserved for my forum posting in the past.

Anyway, shown here are before and after pictures of a BenchMade Mini Skirmish that came to visit me from Hawaii the other day. You can see that as the knife ships it has a neat swirl pattern in the handle non lock side but is a plain jane bead blast finish. Nothing at all wrong with that but the owner of this wonderful folder wanted a bit more and gave me creative license to have my way with it.

First is a re-blast of the handles after disassembly. Once I sat all my hardware aside in a zip lock bag for safe keeping I taped off the detent ball to keep from blasting or anodizing that. Once that was done I took it inside and dipped it at 28 volts for the first base color of blue.

After the blue I went back to my drill press and loaded it with a super fine 3M Cratex Cylinder to put some swirls of my own on the handle in the form of some free hand jeweling of the outer surface in select areas on the non lock side and the whole slab on the lock side. Then I went back to my anodizer and re-anodized only this time at 18 volts for a purple color to blend with the blue. So in the end this is what I got. Honestly my wife wanted it and said to me when seeing it, "for me?" I had to burst her bubble though and tell her it was someone's knife but again quite honestly we were both stunned at how it turned the appeal up on this particular folder. Trust me pictures do not do it justice like sunlight does!

CQC8 HD Conversion

This was one of those folder lock sides sold off to a repeat customer getting ready to go serve his country that needed something faster than the standard turn around time. Some time back I had attempted to make a HD 8 lock side and had it all but done only to discover that the lock side I used as my template was unique in that for some odd reason either the owner of the knife or whomever owned it before him drilled a 'third' hole in it. As a result of course it was copied and I ended up with a second I could not really sell as my best work.

He gladly accepted that offer to get this lock side at a discount but by the time it all played out I ended up having to not just make the lock side for his one. I ended up having to remake the non lock side liner, and another textured black G10 scale to match up to it as well since none of the holes in the back including the lanyard matched up to the originals. Turns out that hole lock side I copied is different than the one sent to replace the side on.

Anyway, as usual I stubbornly baby stepped my way through each step and knocked it out. You can see it here. I did of course have to activate the lock side detent ball since in the rebuild we lost that secondary detent system incorporated into all Emerson liner locks. Also, I tried best I could to camo the third hole so it looks like it is just another threaded hole. I actually did partially thread it for appearance sake only.

Lock side is .160 thickness 6Al-4V titanium and non lock side liner is also the same alloy of titanium only .058 thickness. All the extra parts will be going back with the folder and even though I did have to activate the detent in the lock and drill a small starter hole in the blade for that ball to fall and catch in when the blade closes it can still be put back together just as it shipped from Emerson.

Thanks for looking.

CQC14 HD upgrade for Chris

Seen here is yet another 14 frame lock conversion. As usual no permanent changes were made to any factory parts and the knife can be assembled just as it came from EKI with no more effort than breaking down the parts to clean it takes. It weighs in at 5.7 ounces, feels really great in the hand and once worked in and the washers smooth and polish down the bead blasted surfaces on the inside I'm sure it will be a great user for a long time.

I noted that this model unlike all the others I've seen had a different look to the G10 scales. Its seems flatter or squared off more also. Its hard to put my finger on what all is different from this G10 vs what I usually see and compared to my own model but the color for one is lighter, and it kind of sparkles in the sunlight more. Maybe it has more glass fill than what they used to use. I'm not sure at this writing if this is a change at Emerson or just unique to this later model of the 14. I'm not sure if you can see the serial number in these pictures or not but its up at like 1200 something now and the scales on this one are noticeably different than my early number (under 100) model or any of the other models shown here in my blog or my forum. I do admit its more readily apparent side by side and in person than these pictures show though. Anyway, thanks for stopping by.

Emerson CQC7A HD Conversion

Update and Edit: As a final touch to this folder I did find a single Emerson Skull pocket clip I did not realize I had hiding in my bag of extra clips accumulated over the years. Actually I found some other extra things I had forgotten I still had along with that. One of which was a little pocket hook I had been making a while back to function as an 'add on Wave' for knives equipped with thumb discs but no Wave built into the blade design.

Contrary to popular belief on other forums I do not particularly like permanently modifying a folder I work on as you may know from reading here and on my forum by how I point out the ones that are not permanently modified. I work quite hard to avoid making permanent changes to a knife whenever possible whether its utilizing existing hole patterns drilled and threaded already for one of my pocket clips or a complete rebuild. Perhaps it is the collector in me always in conflict with the pimper in me, I don't know. Anyway, this add on Wave was a 'non invasive' way for me to come up with a Wave that worked and worked well for folks wanting a Wave added to their knife. This comes up quite often with the 7 model from Emerson as of late because a lot of guys like the A spear shaped blade but want the Wave. The latest run which again is limited in number are all non Waved factory blades. If you want the 7 with a Wave and don't particularly like tanto blades or a chisel grind unfortunately you have to buy the tanto chisel grind blade to get it.

Some have sent me blades with the raised areas in the spine for the thumb to rest such as the BenchMade HK 14200, 205 and 210, the 420 Resistor when it was made and of course older 7 A models of Emerson folders all wanting me to cut a hook into the blade permanently modifying the blade. I recall after getting a rather nice and rather collectible green handled 7A here a few years back (those green ones are very rare and discontinued) that I sat down to come up with a pocket hook Wave add on. Also as many visting here may already know, Ernest Emerson, patent holder for the Wave, gave me his OK in writing some years ago to Wave production folding knives for folks asking me to do this for their knives. When I first came up with this add on I had not heard of Andrew Demko but then when Cold Steel ran a production version of their AK47 folder that had something similar I was motivated to contact him about that patent and ask him if it was ok for me to continue to offer the pocket hook pointing out that I had already been selling them albeit just a few. Andy is a class act and gave me his ok. I really like his work. He makes some very stout lock designs too.

I have only done a few of my add on pocket hooks because they are very labor intensive and wasteful the way I had to do them cutting out the shapes on my band saw. The ti has to be longer than what you actually need to allow it to bend easily enough to manipulate and give your tools something big enough to hold onto so you end up having to cut off or grind off some waste after you heat it up to form it to a hook and you waste quite a bit just to get one of the shapes out of a sheet of titanium. I have not been taking orders for these for the last year or more due to this but now that I have made friends with Dave over at Great Lakes Waterjet who cuts out my pocket clip blanks perhaps he can cut these out for me from my sheets of titanium also. I did not have the pattern anymore for thesee or so I thought. I just figured I had sold them all but found this one laying in a box with the skull clip so it got added to this folder as a break in helper. Its worked quite well too and been fun.

These removable Wave hook/thumb discs do work quite well and I've found they are very gentle on pockets compared to other Waves so I feel they would be appreciated for that. There are other minor advantages to having a removable Wave for traveling also, particularly through certain states in the US. Some of the folks that bought these add on Wave hooks from me also bought low rider pocket clips so when they removed the Wave they could at the same time install the pocket clip and reinstall the original thumb disc. When combined with a khaki color or blue jean color anodized pocket clip this offered them some comfort in providing some perceived 'urban camo' for their carry knife in those not so not so knife friendly areas.

This Emerson model is 4 and 5/8" closed. What you are looking at is a CQC7A shown here with a factory non Waved blade. This A model is one of the limited run of Emersons just produced recently as I recall. This one is done in .140 thickness titanium for the new lock side. I've taken the lock cut relief in the back of the lock down to .060 on this one to spring the lock compared to .033 for the lock cut relief on my Emerson Comrade 12 model. Again here with this one, no permanent modifications were done to any of the factory parts and it can be reverted right back to the factory liner lock.

I do have a puzzle with this one I'm still scratchin' my head over. All the .160 plus thickness slab models of the Horseman folders I posted earlier weighed in at 5 ounces plus or minus each. This folder done thinner than those by .020 for total titanium thickness weighs 5.1 ounces as shown here. I'm not sure why or how but that is the case. This titanium slab was more difficult to thread compared to the thicker models although the Tapmatic didn't listen or care much about all the whining though so maybe its just denser or something. Not sure.

Lock up is early and secure. The feel of the action is smooth as silk already even though its only been used a few times at this writing. You may also notice this one was not ordered with the replacement stop pin conversion like others I've posted recently. These Emersons are great knives folks! Every knife nut should own at least one CQC7 from Emerson or at least an early BenchMade model from when Ernie worked there. This model, much like the maker are both a legend in their own time.

This is the model that perhaps single handedly revolutionized the tactical folder world. Of course it did that with the Tanto blade shape and forever put tanto blades on the map for good in my opinion. Emerson makes a Waved version of this same folder which I've rebuilt the same way on an earlier post some months back. That model comes with the Tanto blade but both come with the same handle choices in three sizes. One in Mini, this model here and a Super which is the larger of the three.

Oh and for you knife nuts out there, yes I recognize that the late great Bob Lum cannot be forgotten when it comes to the tanto blade and introducing that to America but what Ernest R. Emerson did for it is beyond measure with this model.

Thanks for looking.

Khin's Horseman HD

Ok last post of the completed folder upgrade to a slab lock side. Note there are three sets of pictures loaded at different times in this post and three postings even though they are hard to discern. First four pictures are one post. Then we have the one off picture smaller than the others done with my scanner showing the original stop pin in the folder. After that is the last post which is the one that shows the folder before I even took it apart.

In this picture show of the folder before and after you can see the original factory liners pictured along with the original stop pin and the new lock side and sometimes other parts that I add to the folders I work on, parts which I've now replaced with some custom made ones at times which as you have seen before can be spacers to replace the black original one shown in this knife, or pocket clips custom made or even new non locking liners and scales. So, I hope this helps some of those that weren't following what is going on when you see me posting like this showing a lock side of a folding knife you can now get a better idea of what it all adds up to.

You can see here that just as I had hoped it would the folder went together this morning no problem. Now all I have left on this one is to create my custom replacement stop pin to replace the original placed in the slab temporarily to test fire the lock and once thats done I'll take a couple better digitals and ship it home. This folder got a new lock slab of .160 thickness and as you may recall, it weighed in at 4.7 ounces before starting. It now weighs 5.1 ounces on the same digital postal scale I use for weighing packages before mailing them.

I've also activated lock side detent ball on this knife per the request of the owner. A request that comes quite often from New Yorkers.



Some of the non knife nut folks have asked me in email some questions that prompted this before and after of what I am actually doing here. I guess I take it for granted that most folks just know but some say while it looks great they are not exactly following some of the work with no reference to see the folder before I start whatever I do.

So, with that in mind here are some before pictures of the next folder up on my bench. This is yet another Horseman. Four in a row now which is a record even the CQC14 has never matched. The 14 is still the most frequently requested folder that I get asked to convert with upwards of some 20 plus for just that model by itself but I can't recall ever having four back to back orders of the same model before no matter what manufacturer it is.

Well, to the point of this post here, I took a few shots of the folder before disassembly to install the lock slab shown here beside it. I made this slab side by side to fit today as I made the one posted just below it. They are basically twins so I left the one together so as to not mix up parts. Tomorrow when I can get back to the shop fresh if I did all my homework correctly this slab should simply screw down and be ready to roll. We'll see. :-)

Shown on all sides is the factory folder belonging to Khin. This Horseman here weighs in at 4.7 ounces as shown here. As you may recall most of these are weighing in at 4.9 to 5 ounces once I add the new slab so there is a nominal weight gain but is negligible considering the advantages the slab side brings to the table. Heavier duty, and higher reliability being just two. Lets not forget the 'cool' factor besides that. Maybe these shots here of various angles of the slab I have shown here to fit and the original can give you some better reference to gauge the actual work being done. Thats my hope anyway.

By the way. You may notice the slight depression on the non locking/non pocket clip side near the thumb ramp to access the opening disc on the blade. This is a modification done by the owner of the knife not factory done. Just so you know. I assume he did this to help his thumb out so it hits the thumb disc square instead of skipping over it, since the disc is not centered in the hole area when the blade is closed. I've noted this on other Emerson models and can't say I know why that is the case but my Specwar folders from 1998 and 1999 are both this way also. If you scroll below to the ivory Horseman you can get a good shot of the folder closed on the ivory side to see how the thumb disc sits on the blade with the blade closed. Many makers would put that disc dead center in the half moon recess cut out on that side of the folder for the thumb to access the lock but Emerson moved his slightly off. Knowing Ernest there is probably good reason for this. Perhaps something to do with the disc cactching on pockets instead of the Wave or otherwise interfering with how it is designed to work. I really can't say I know the answer on this one. Personally its never been off enough to bother me much but I know other Emerson owners have mentioned it to me in the past.

Bull Pivot Barrels, Bull Stops, Super Duty Hardware and Thin Lock Cuts

Shown top is a production Emerson HD7 mangled at the point most all frame locks fail when stressed, showing what happens when one gets stressed to the point that something has to give. There is a large variance from company to company and from knife to knife in location of the lock cuts and how they are done but one thing they all have in common is that they are taken down pretty thin at the lock relief where we makers bend the lock to put spring in it.

Here we have two Emerson HD7 models done in different years. Note the different lock cuts both in the way it was done and for the location.  These variances occur in many models across the board and from makers.

During testing I've done, some very thin cut frame locks collapsed like that top picture or worse at 65 to 68 pounds of free weight hanging on the end of the knife. None tested made it to 100 pounds. Some liner locks actually hold more  weight than frame locks done like those in that picture. A strong liner lock will hold 100 pounds. A strong liner lock like one in stainless steel .080 thick may hold 130 pounds but even that depends on if it has thin lock cuts, no lock cuts  and many other factors. 


Contrary to how many readers may feel about that picture above. That my friends is a design that deserves praise for defeating the way it was engineered to go. That HD7 above did its job and so did the designer/maker of the knife. I doubt any sutures or ER trips costing great amounts of money were needed with that defeat. We should all pray to be so lucky should we be the on the unfortunate end of a defeat ourselves one day.

How and when a lock fails just depends on so much including the length of the knife tested and the blade length, lock thickness, lock material the lock contact and more. As you may have figured out that 100 pounds ain't much weight compared to many of the locks we all see these days being tested on youtube using different lock types. Triad locks by Cold Steel for example will hold two to five times that weight listed above in the same tests and fair better in about all other tests as well from spine whacks to overstrikes and more.

Still though there are other advantages to frame locks in that the hand helps the lock to absorb some of that shock it may see in use that cannot be duplicated to appreciate when doing static load (free weight hang) tests and in the hand the frame lock can and does do an aweful lot of hard use jobs. Even a frame lock with the contact worn such that there is clicking from the up and down blade play from the wear does not prevent the knife from being used and even used hard. Its still my personal favorite type of lock because it need not hold a house on the end of the knife to be useful guys. For one frame locks are usually thinner in the pocket carrying easier even when extra long and they are open designs and as a result they fair better in muck than other designs!

Don't let it sway you from a liner or frame lock just because this can occur. Its still a very good design for most all things we do with our knives. Do we have to take the lock cuts that far down in the frame locks? No we don't. I personally wish makers or manufacturers offered some kind of tough use option or "He Man" option of their own to allow one to get a knife a bit stiffer and thicker. Its too much to ask though. I've sold some done that way that folks have returned for me to thin more with more profound lock cuts so they were not so hard on thumbs. Its not for everyone to leave the lock cut thicker. With lock cuts left thicker comes a host of other things.

Done with cuts left thicker it will not be a flipper blade unless you licensed IKBS. The detent ball really works and holds the blade closed well when the lock is stout because when the lock is stout the spring tension is too and sometimes the spring tension is such that you can really feel and hear the ball on the blade and other times the lock is so stout that if you are the type that likes to flick your knife open and closed a lot its just going to cause pre-mature carpel tunnel and a really sore thumb or a really big callus if you keep it up. You'll also notice flattened detent balls on the lock a lot quicker when the lock is done this way.

Makers and manufacturers have to please a lot of folks. Its better if the action is easy and smooth and thats what everyone wants or they'd complain about it. So these makers doing a lot of these and manufacturers trying to appeal to a large audience do what they feel is needed to make it strong enough to serve the owner, yet weak enough to be easy to use easily and with comfort once the knife is broken in properly. It doesn't happen often but it happens and try as one may to warn of it some react with anger at times when these things are pointed out. Its not often easy to look at your own favorites with the same eyes you use to view the not so favored. 

I've said before that if people would just for a moment take off the blinders spending half the effort examining the knives they love with the same eyes they use to pick apart knives they hate maybe then they will see more objectively for what is right in front of them instead of being blinded by bias, but unfortunately that is often times like asking someone of one religious faith to examine their own the same way they examine and pick apart opposing faiths. It just isn't happening. With some the bias is so strong that no matter what you tell them they don't want to hear even what amounts to common sense regarding their favorite lock type. 

Like any chain there is a weakest link and any chain is only as strong as its weakest link. In liner and frame locks that weak link is the lock. It doesn't matter how much you beef up the other parts of the system because they have no effect other than making that system more out of balance if the lock remains the same. You can stick a bull pivot 1/4" in diameter in there and you can put a bull stop pin 3/16" in diameter or larger and coat it with G10 scales and a super duty set of screws in it. But if the lock is still a gents liner lock in .045 thickness under all that coating its not advanced one bit more really because those locks are still the point where the knife will fail in say a free weight hang test.  Whats more it would probably fail at the same point it would fail if the knife had bone handles and bolsters and a 1/8" stop pin diameter with a 5/32" pivot barrel using that same lock! 

The truth is even a 5/32" pivot and 1/8" stop pin would still be stronger and outlast most locks in a free weight hang test of this lock type. Some companies have put bull pivots and bull stop pins in their knives ever since they realized they sell better in what I call 'wolf' clothing and while we can't ding them for some marketing to sell their wares we can see through it if we take time to look deep enough.

I attributed it the other day privately to a guy like this. Looking at it from the stand point of an automobile lets consider and say for arguments sake that a gentleman's liner lock is like a four door Ford LTD family sedan. (I'm sure some old farts out there still know what an LTD was) Now you can do a lot with that car as it has a big foot print, a big trunk, a powerful motor, a wide track and comfort for the driver and while you may be able to toughen it up by sticking balloon tires on it, and a cattle guard bumper on the front and even by painting it camo in a hard coat shell with a couple tactical spot lights on the side for hunting and a deer rack on the roof with a winch up on the front bumper but its still a Ford 4 door family sedan underneath and it always will be.

Thats the myth of bull pivots, bull stops, G10 scales, tactical looks and grips, and whimpy thin long locks that were never designed for what they are used for in a nut shell description. If its still a gents folder starting out on the frame, all that nice hardware hasn't really changed it. If the four door sedan has all that great stuff you may get a little further up the goat trail in it thanks to those bigger tires but it will never be the four wheeler you really wanted. Like I said, sometimes the truth sucks. I think people feel this intuitively when they would mail me work to convert from thin flexible to beefy stout. In some of the cases where the locks replaced were .050 or less in thickness the trade off even with a huge lock cut still favors the rebuild with the only drawback being the cost to do the job. 

For what its worth even though a frame or liner lock can fold, kink, or bend and deform similar to the picture shown here these are not the most catastrophic defeats of a lock that one can experience and one could argue that makers create the circumstances such that if and when the frame lock or thicker liner lock type knife gets stressed to that point of something having to give then they'd rather it be programmed in so to speak so this is what occurs just as shown in the picture above of the mangled lock. Of course this relies on the makers skill at creating a perfect contact that allows this to happen instead of the much worse opposite where the blade is free. My contention is that in the hand the frame lock is very unlikely to defeat once gripped properly. 

If you are going to have a defeat I guess what I'm saying is that this would be the way to do it as opposed to the way that requires sutures and costly tetanus shots and more. Most of the time the blade is still opened and locked in this type of defeat albeit permanently with defeats of this type on some until you disassemble the knife but so long as fingers are not cut bad and maybe a bad pinch and a bruised ego are the worst of your problems followed by some choice words usually reserved for sailors its a not as bad a lock defeat as other types of defeats can be.  

As you can see from most of my old frame lock conversions I used to do a lot of my lock cuts to spring the lock just a bit different than most you'll see from other makers. For one mine are left thicker at the lock cut usually and as a result of a customer requests for me to do that. In fact it was people that bought frame locks from other makers/manufacturers and liked them but wanted more that led me to looking more into the lock cut. My first question to myself was why not do one without a lock cut so thin? Lets see what happens. At other times I was contacted by customers who wanted a folder converted from a thin liner lock that they could feel flexing in use. This turns a lot of people off to have a tactical folder they can see the lock flexing on and so the request was to convert these to a beefy frame lock. I simply filled customer solicited requests to get me into this. I've always felt the frame lock sides I did were stronger simply because you could feel the difference in spring resistance quite a bit and they certainly required more ummmph to release the blade. Then there is the visual thing. They do look the part of beefy and to some just the look of beefy is more important than whether it actually is which again plays into that bull pivot appeal! Boy they wore on the thumb and flattened a detent ball good and quick though! So, I'd probably put a shallow lock cut not so drastically thin in a frame lock made for my own self. Some have asked me what is the best thickness for a lock cut in a frame lock folder or thicker liner lock folding knife. The truth is you could ask a thousand makers and get a thousand different answers I think. I like about .059-.060 personally. You can certainly get by with thicker though. 


My point is and always has been that the point of catastrophic defeat could be stretched out a little bit more than 68 pounds just by simply leaving the lock cuts a bit thick on the frame locks for customers wanting it to make them feel better about their folder but I think most makers figure that even if left the strongest it could be the lock is still the point of defeat and it may hold 130 pounds max if you are lucky unless you use the thickest materials you can use and even then the lock cuts negate a lot of that strength! With some tweaks and planning the overall strength of the folder could be more balanced by strengthening the lock some to try to get it closer to what the other parts of the system are already at but no matter what you do the lock will never catch the other parts of the system for strength. You have to go to a different type of lock to get that. . Make no mistake no matter how much you love the lock. When talking about liner or frame locks, the lock is still the likely weak link in the chain regarding the system, A/K/A other parts of the folder. I like to think I've just improved that weak link a little bit more to bump it up to a bit more capability by leaving my lock cuts thick rather than thinning them down so radically just to make them amazingly easy to move but also just as easy to hyper extend the lock out the wrong way if one were to take the pocket clip off or pull their clip to make it stand up from the folder higher so it doesn't grab pockets so tight. Most clips act as a block for lock travel and while they don't always work that well if you notice you'll see that many makers incorporate this double duty aspect of the pocket clip with their frame locks. 

Just because I did some of my frame locks with thicker lock cuts does not mean the same thing would not or could not happen with one of my folders as what you see in the picture here above. In fact it is likely it still would happen to one of mine and very similar to what you see in that picture above should mine be pushed to the same limits only by the time that happened to mine you would really have to stress the knife to double or more the force that it took to even begin to duplicate a situation like shown here. That isn't bragging. From my stand point it is simple physics. Oh I realize my folders may not open quite as silky smooth with my lock cuts left as thick as some of them are but if thats what folks wanted they'd buy the knives someplace else instead of seeking me out.

For at least the few folks that have used me when I offered these conversions they wanted beefy and strong and were not too worried about a knife they sat around flicking opened and closed all day long like a replacement habit for nail biting. They pull the knife out when needed, it does the job, they put it back and they feel a little better about knowing that if they really lean into it that it should take a bit more before the lock ever reaches this point but its not changing the fact that the lock will still be the first thing to go for a controlled burn so to speak.

If anything, the way I do mine with an 'air bag' built in for a safer defeat of the lock is still engineered into the design so that should the system get stressed to that point of something having to give that it would still go just as the picture above using one of my knives too. This is what shows quite vividly in my testing even though it takes a bit more stress and strain to get mine to that point compared to most others I have bought built like above, and that is due to how I build them regarding the thickness and the flatter lock contact I use for the lock itself which makes it more stable on the blade. The funny thing is I use a 3/16" pivot, and a 1/8" stop yet my knives test out stronger than all I've tested with bull hardware and thinner locks once again proving that the weak link is the culprit no matter how much you advance the other parts of the whole.

Lastly, its not really a weak design even made as shown above with all that titanium taken out of the thickness in the back of the folder. Can it be better? Certainly it can be more balanced in the system that makes up the folder parts yes but so long as you still design the knife and engineer it such that the lock would go first and hopefully just as shown above when it does reach that point of something has to give when the system gets stressed, I think the frame lock design is the most solid of those being used today. Which once again illustrates why I like the frame lock so much for all it brings to the table. You don't hear about defeats of this nature often enough to the thin lock cuts to be a problem so therefore I'd say its really not a problem to concern yourself with. If however you feel you want one that just looks beefy discuss it with the maker and maybe they will compromise with you to give you some visual appeal with the lock cut done slightly differently on your folder. Never hurts to ask. 

While I'm a big big fan of the Triad lock and all it brings, and I can say I own enough of them now I want to stress that frame locks are still one of my favorites among locks in folding knives. Even though it is most often not even as strong as some liner locks I find they are strong enough and to me they are much more reliable giving a sense of security once your hand is wrapped around it good. Of course some models prevent this hand wrapping of the lock by the position of the pocket clip so not all instill this confidence for me personally. I found some like the JYDII to be particularly appealing in frame lock due to the flipper being out there when its opened. It is hard to imagine the blade coming back to bite you on one of these flipper models even in one of the liner lock models. In this case since you'd get a bad pinch at worse case scenario I'd have a good feeling carrying one of these even if a liner lock. I like knives with the choil built in because when you have a choil and the ability to position your index finger in front of the pivot it is also hard to imagine it defeating if your finger is there blocking travel. In a way in these grips the knives become a part of the hand allowing greater versatility with that sense of security so I personally find this so appealing that knives offering either flippers or choils in frame locks of this type are my main knives to carry most of the time as my primary EDC. I have the one Triad locking model in my rotation in the way of that Mini AK47 which I do tend to favor. Its always partnered with something though as the mini AK is my left side carry piece coming out in reverse grip most always for fun with that thumb plate on it. I love that thing! Anyway, the other pocket always changes and it may have any number of frame locks from day to day or other liner lock type folders with built in choils or flippers. I like those and favor them again due to that feeling they are just inherently more reliable by design. I mean can you imagine the ZT0551 even closing on you in use? It would be a bad pinch at best. Can't argue with that in my opinion. 


 The way I have seen some lock backs break when stressed it seems obvious this type of lock would be a more disastrous defeat. Based on how a lot of people use their Cold Steel folders it seems to me that when a Triad does fail that it is likely to have a great deal of force and pressure applied to it to make that happen. This could be quite disastrous in the hand and it would be more likely to really mess up the user as well as itself when it happens. So in my final analysis as much as I love the Triad lock, the frame lock design may in fact be the overall higher rated lock for effective and safe use compared to all others because its more in balance with the abilities and strengths of the human using it..
