Thickest Strongest LINER lock?

on a well built knife i have no fear of either failing on me here is a comparison pick of the framelock of a zt 550 (thanks again chris) and the locking liner of the spyderco gb. both are stout and beastly 004.jpg006.jpg007.jpg
 
I'm not worried about Frame lock or TI liner lock knives failing. I've only had a couple of liner lock knives fail and that was because of abuse or extremely poor manufacturing. I've never abused a Frame Lock knife so I don't really know about them.

I was kind of sort of drinking a lot when I started this thread. I guess mostly I wanted to see some really heavy duty liner lock knives. It don't matter much though because nothing (outside of a fixed blade) is going to keep me from carrying a TriAd lock knife. :D

Hey, it doesn't make you a bad person. :)

Now, on the Triad Lock, since you mention it... I've recently picked up one of the new Cold Steel XL Voyagers with that lock. Rock solid, though I have not had a chance to put it through its paces. Question for those who tote anything with a Triad Lock: does it develop any play, even the slightest bit in any direction, over time and use?

Just curious, as it seems like a pretty solid design that accounts for wear and tear to some degree. Thanks.

So after doing some reading I have found out that Steel is potentially twice as strong as Ti of the same size/volume. BUT, of course ALL steel is not stronger than ALL Ti.
TI tends to be much stronger than Steel per Weight. But tends not to be nearly as strong per size or volume.

So if you had a TI Frame Lock made of Steel if would be stronger (assuming a good steel and heat treat), but much much heavier.

This post has given me the motivation to build my first framelock. I just ordered some 3/16" ATS34 and by God, I'm going to make framelock folder out of it.

I have a heavily modded (and carried) Spartan and it still locks as tight as it did from the box. No movement in any direction.
 
Interesting, thank you CM.

I just wish beyond wishing that the Triad Lock was available on upper-range production knives. Or that perhaps Mr. Demko would start making mid-techs. :)

I used a 4 pound cross peen and my American Lawman to make a wedge out of a two by four once or twice. It did not develop blade play afterwards. (Sometimes you gotta do what you gotta do)
Then last summer I tried it for throwing practice. I did get it to stick several times from about 7 feet. But it also bounced off of rocks a few times as well. (on a side note, my nephew and I also got a full sized axe to stick at about 40 feet) :D Anyway, it has a tiny tiny bit of blade play now. There is no side to side, just a barely perceptible up and down. Which is due to a bent stop pin. I suppose that I could fix it, but the amount of play is quite small. YMMV
 
Hossum Retribution 2. Thickest titanium liner lock I know of.

The point of the video wasn't to say that liner locks are stronger than frame locks. It was meant to show that liner locks are just as strong given that the lock thicknesses are the same. (in example: the frame lock cut out is the same thickness as the whole locking liner) :)

I don't know about productions, but I've seen some seriously thick and beefy liner locks in some custom knives. I'm about to get a burnley/krein Raven which has a beefy Ti liner lock. Should be a cool one!

This isn't really true. A first year engineering class may be in order. The shape of the lock, length, thickness, and design of cutout all have to be taken into account. A thin liner lock can potentially buckle while a thicker frame lock probably won't. It is not as easy as saying the cutout is the same thickness as the linerlock so they must have the same strength.

I would be willing to bet framelock cutout placement is more important than cutout thickness when it comes to lock strength.

I'm also glad the strength of ti and steel was pointed out. Ti is strong for its weight but is not lighter and stronger. Generally speaking since there are many alloys of both.

IMO there are much more reliable locks that are anywhere from as strong to many times stronger than frame/ liner locks. I've had way to many issues with frame/ liner locks to put much faith in them when there are much better engineered locks available.

You must not have watched my vid. What I say here is kind of out of context unless you watch the videos. I covered everything you just said. :)

But, a thick frame lock doesn't matter when the cut out in thin.

My point is that given that the cut out in the frame lock is the same thickness as the whole liner lock then they will most likely be equally strong. A 5 mil thick lock bar is cool and all, but it's only as strong as its 1 mil thick cut out.

At any rate, none of us can be right or wrong, unless we have real world evidence and experience to back us up - which none of us do.........So, it's just all a fun debate. No one is right or wrong.
 
So what CrimsonTideShooter is saying is that we need to go break some knives! In a scientific type of way of course.

You guys seem pretty sure that Ti is stronger than Steel. I thought it was the other way around. I guess I need to do some reading.

TI is stronger than steel per mass, not per volume. A frame lock made out of steel will be stronger than a frame lock made out of TI that is the same size, unless your comparing the higher quality alloy to lowest quality steel. Apples to apples, steel is stronger per volume; the reason TI is used is because it can be nearly as strong as steel with the same volume, but much less weight.
 
I just wanted to point out that I also read ChrimsonTideShooter's comments in his voice with the Southern Drawl.
 
is there a psychological factor here? it may just be my poor comprehension but some forumers are not confortable with certain locks and that will count in an emergency (or going into an emergency) situation. based on my informal, private survey, the locks that give users the most confidence is given below in decreasing order:

triad (would tie with a strong balisong but the latter has deployment issues)
axis/bolt lock
integral (assuming good design and manufacture)
spine lock (also assuming good D&M)
liner/compression lock (regardless of quality)
***
am i making sense?
 
I think people have more faith in the Compression lock. Probably about the same as the axis from what I read on the forums.

Lol, don't know if that's good or bad. Believe it or not, most people around here comment on my apparent lack of a southern accent. If you heard some of the people around here you'd think I was normal. There are some SUPER redneck people in AL. Haha
