DemkoKnives, do you custom knives outside of CS? sorry if that's a dumb question, I'm kind of just getting into knives

You don't explain it well and I don't think tf8s understood that. How does it distribute the loadings?
The blade stop takes the forcers from the blade in the opening direction and transmits the forces to the frame.
This removes that function from the lockbar (as seen in conventional lockbacks), allowing a more "optimized" lockbar to blade engagement.
Then, to add to the improvement, the lockbar is wedged between the blade-notch and the blade stop, a structure not possible with a conventional lockback. That bit of play in the lockbar pivot allows this wedging to occur more readily. Wedged in, the closing stresses are transmitted to the frame via the bladestop, the lockbar pivot, and to some degree the blade pivot. A "triad".
And, compared to most of the lockbacks I have had apart, the lockbar of the Tri-Ad locks do enter deeper into the blade notch and do have a greater angle of engagement.

Me too. I don't really get what folks have against AUS8/AUS8a. I can easily get a screaming sharp edge that lasts just as long as most other steels. I have knives in everything from 1095 to ZDP-189, and I love AUS8.
Yeah and it's very easy to maintain it too getting it back to scary sharp in just a few mins. :thumbup:

Its pretty obvious that the how is by the stop pin. The Triad locks on the first run don't sink as deep as the last change when they did away with the liners. The Manix, and Mini Manix both sink quite deep and have angled contacts to wedge the lock bar in the blade contact better. I agree its not the Triad lock wedged on a stop pin but it is wedged on the contact. The fact that the stop is there is the only real difference I see in how its designed speaking of the actual design of how the lock contacts. The lockbar itself is shaped basically the same on both. And I believe I said it distributes the forces throughout the system. System being the pivot, rocker arm pivot, and body of the folder along with the rest of the assembly screws. If you just need someone to point out that those three points make a Triad then so be it. The Triad system is not new to knives. The three point contact makes up a frame or liner lock and basically every other lock in use in folders. The difference between the Triad lock and these other three point contact locks is that the Triad distributes forces throughout the system.

Hmm. Is there any real benefit to laminating such ordinary steels?

STR and/or Andrew (Mr. Demko), I've noticed that the newest version of the American Lawman (the all G-10 version) has the stop pin placed lower (closer to the pivot) than the original, steel-lined version. I'm wondering if this was done as an improvement, for the sake of wear, or whether it was done to boost lock strength, to negate the fact that the handle no longer has steel liners backing it up? If either of you could enlighten me, I'd be most appreciative!
:thumbup: I agree I seriously dislike Lynn Thompson. I dislike the fact that he advertises low quality knives as the best of all time. Yes, I have had horrible experiences with Cold Steel knives and IMO they are low quality and are not adequate for my uses.

I've asked myself (probably the wrong person to be asking) the same question, as AUS-8 is a plenty tough/ductile steel to begin with. I think any extra advantage in toughness or ductility would be pretty marginal, though Cold Steel has, in the past, claimed their original San Mai III yields a 25% increase in toughness over their AUS-8.

Why don't you describe some of those experiences, or at least post links to threads in which you've previously described them?
That's what I was wondering, but according to many here, AUS-8 and VG-1 are EXTRAordinary steels
Why don't we go ahead and laminate 440A and 8Cr13MoV while we're at it?
I guess I should put the disclaimer here that I don't hate cold steel although those select few will say I do anyway.

There is a common saying "to assume...."
I doubt if tf8s understood what the term "system" was meant to be and I sure didn't. Forces are distributed throughout the system. And? By what? And how does this distribution make the lock stronger? Even based on this most recent discussion I'm not sure what you mean by "system". Are not all knives closed sytems and, therefore, are not the forces "distributed" in all knives. "Energy in = energy out" and all that.
So, are you saying that merely adding a blade stop pin, with no other modification, will make a full-size Manix as strong as a Rajah II or Spartan? I note that making the lockbar wedge between the stop-pin and bladenotch is more than merely adding a blade stop-pin.
"And, compared to most of the lockbacks I have had apart, the lockbar of the Tri-Ad locks do enter deeper into the blade notch and do have a greater angle of engagement."
I do note that the term "most" is a conditional, broadly interpreted as being more the 50%. The Manix is not an average lockback.

Put in ultra-locks, drilled out SS liners, G-10 scales so you can actually use the pocket clip, get rid of those weird disks for thumbstuds and use the volcano style. Straighten the grips back out to normal again.
Those grips are wrist-breakers and deal-breakers for anyone who knows how to use a knife for anything other than smashing it into something. They're ridiculous and made, IMO, to entice wannabe knife wielders into thinking they're super cool when they're the exact opposite.
I've been on CS forum and found the folks to be extremely nice but mostly clueless on how to use a blade. They think bigger is better and shiny and bigger is even better....more's the pity.
Looking for CS to come down to earth. Lynn Thompson is a marketing genius, I admire his extremely sharp blades, strong locks but why keep making zanier knives instead of refining his existing line-up?
Why don't you describe some of those experiences, or at least post links to threads in which you've previously described them?
I've had that ultra lock (axis lock rip off) fail on me two times because how cheap they were made. I have also had all of my CS knives develop vertical bladeplay after about a WEEK of use. The edge hasn't held up well and has chipped too easy due to bad heat treatment. Last but not least I've had three CS knives that have chipped tips due to dropping it from a three foot coffee table one was a tanto.
I will repeat it once again CS knives have been crap in my experiences. Your experiences may vary.

Well, I generally use my less expensive knives hard with no remorse. Lynn Thompson advertises all CS knives as extreme hard use blades and I'm not impressed.

Most knife nuts are quite familiar with the parts of their folders. Its a pretty good "assumption" on your own part to figure that the gent that asked me directly a question and then thanked me for the answer didn't know what I meant in any part of what I wrote. What you ask has already been asked and answered and apparently you already know the answers you seek so I fail to see the need to cover it again. If you missed it earlier I said the forces are distributed throughout the system, that being the parts that make up the folder IE, pivot, stop, rocker pivot, G10 and body screws, blade and so forth. The relationship between all these parts makes up the system. As for how that makes the lock stronger. That is not what I described. It makes the forces distribute away from the lock so that they are shared by the other parts of the folder starting with the stop, so the lock can do what it is already capable of doing which is securing the blade against negative pressures while the stop pin absorbs positive pressures that normal lock bars would absorb on their own. And yes when its done this way of course the body of the folder still absorbs some of the forces but most of it is going right to the lock. Again though that information is already out there readily available. You seem to know the answers you are asking about so I don't know why you want to assume for all the others that they don't know or what your motivation to ask me about it is other than to win the argument that I don't describe it well. Fair enough. I obviously don't describe it well enough for you so you are entitled to that opinion.
No I did not say anything about adding a stop pin to a Manix or mention what it would do to it if you did. In fact that is mere speculation and not something I even went into. What I did say was that the shape of the way the lock connects to the blade and how it wedges in place and also sits up high enough to allow a space under it matches up to the same shape as that of my American Lawman. The fact that one wedges against a stop and one wedges against the blade is the main difference other than the way the stop absorbs forces the lock absorbs on the other.
If you didn't follow "system" when I spoke of the parts and mentioned stop pin, bull pivot and other things even in my earlier posts I don't know what to do to improve your perception my friend. I feel like I covered it well enough to give details that satisfy the majority and if not my apologies. I tried.

That he does, bends them in a vice with a pipe over the handle. You should send them back. I had a bad old style voyager plastic pocket clip and sent it in and he sent me a brand new voyager.
What exactly is lame about them, I thought that he made a deal with Benchmade to use the idea? Anyway, why are they lame?
