Thickest Strongest LINER lock?

I think people have more faith in the Compression lock. Probably about the same as the axis from what I read on the forums.

Yeah, the compression lock is fantastic, I like it more than the axis personally, no springs to break and is SUPER smooth in the para 2.
 
I would have to give a nod to the Gayle Bradley as well. But for Titanium, the Strider/Buck spear point is stupid thick.

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.

No I didn't watch the video as there was no link. I was basing what I said on what you said. And saying a frame lock with a cutout the same thickness as a liner lock are similar in strength, is probably going to be wrong in just about every configuration. A long thin liner lock can buckle (there are formulas to predict) along the whole length of the lock. While the frame lock only has a small cutout and by definition can not "buckle". The thicker part of the frame lock is obviously stronger. The weakness at the cutout will come from it being a stress riser and lock forces having to move around and through the cutout. The forces required to fail should be significantly higher than the characteristically low forces required to buckle a long, thin liner lock.

Of coarse we don't know how every knife will behave without extensive testing, but fairly accurate predictions can be made using some fairly basic engineering principles. I think you will be very hard pressed to find a liner lock that can support equal (or anywhere close) forces to a similar frame lock with a cutout the same thickness as the liner lock.

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

It's a good thing man (and I hear you on the accent - I get the same thing here in Oklahoma).

I've had both the Shallot and storm, I liked the shallot better but the storm was still nice, both had pretty thick lockbars but i believe the shallot was a bit thicker.

the 0350 is steel and plenty thick for whatever your doing, it's a total workhorse.

I have an 0350 and the liner lock is a beast, it wont fail you
 
You didn't take into account that a liner lock can only bulge so far before contacting the scale material, which in turn distributes that force throughout the whole knife. Liner locks are limited as to how far they can flex due to the scale.

I have actually tested this theory with one of my Emerson's. Bent the lock so far that it contacted the scale, and couldn't bend it any more with all of my strength. After I was done it sprung back to normal with no damage done. :)

So you went and tried closing the blade with the lock engaged? Video?
 
Strongest liner lock? For me is CS Spectre, no doubt. It has a thick, short ( with no cutout ) and "reinforced" Ti lock. I'm pretty sure that is as stronger as a frame lock, at least...
 
that could be, the CS ti-lite with 6" blade that Demko tested on video looked very strong and solid with the same folded over linerlock. The 4" ti-lites that guys around me used in the field were pretty solid.
 
Destruction testing done years ago (rec.knives) on a variety of lock styles and steels (including Ti liner locks) by Benchmade when Mark McWillis was VP basically made the point that in a folding knife with a well made lock of any style the point of vulnerability was the blade/handle junction. That is where force is very high when a knife is being used hard or (in this case) abused and there is often a stress riser that facilitates a break. This was even true with respect to relatively inexpensive handle materials (Zytel, G10, plastic). Knives, esp. folding knives, have beefed up substantially since those days so it is even less of an issue today.

Nice to know, but kind of puts a damper on parsing the merits of locks and handle construction. If you have a reliable lock of virtually any style or material you are GTG.

Don't worry about the liner material, the handle material, the type of lock....it is highly unlikely that it will ever be an issue.

Mark,
The whole point is to push the limits. What else can I do with my pocket knife? I already posted about using my American Lawman as a (small) splitting wedge, and a throwing knife. So far it's held up really really well. But a fixed blade would still probably have held up better. So there is more work to do.

Throwing a folding knife isn't "pushing the limits", it's abuse.
Not one folding knife maker approves of this practice, not one.

Some of you guys need to start making your own folders to prove the well established manufactureres wrong. You all know and demand so much.

Go ahead, we'll wait.

Cliff Stamp never took the challenge either, but he talked a good line and lectured knifemakers all the time. Yet, he never made a knife.

You are comparing me to Cliff Stamp? Really? :thumbdn:

Heck I want a truck that gets 400 miles to the gallon, doesn't mean that I have the free time to build one.

I didn't say that throwing a knife was a good idea, and I didn't say that it wasn't abuse. When I said "pushing the Limits" I meant the limits of lock strength. I'm not a knife maker and I'm not an engineer so I can't say that I know how to make a stronger lock. But I'm excited to see that knife companies are trying.
