Any folding knives built as strong as a CS Spartan?

I think there's a fair amount of evidence demonstrating that the Tri-Ad lock is one of the strongest on the market. As for being able to support 500+ pounds, I was told by a Spyderco rep that in their testing of the new model BBL on the Manix 2, the knife supported over 1000 points at the pivot, at which point the handle disintegrated, while the lock remained fine. That's pretty darn good to me. I haven't heard much in the way of claims about the compression lock, and to be honest, I am unsure why it's supposed to be stronger than a liner lock. The physics is very similar, and they're going to fail in the same way. I don't think the AXIS lock is going to be quite as strong as the Tri-Ad or BBL locks from the tests I've read about, but it still is a VERY strong lock, and by far the fastest of the three.

First of all , saying the AXIS isn't as strong as the ball bearing lock is laughable
The AXIS is light years better , stronger and by far more proven and reliable lock
I really don't know what so called "tests" did you read , but I would LOVE to see them , please post them

Second , Spyderco can claim whatever they want , but so far they are refusing to back up their mouth with actual evidence , which is some really weak shit in my opinion


Compression lock isn't any stronger then well built and executed liner lock or frame locks (such as ZT) , and it is basically just a vulnerable to same issues and failures liner and frame lock can suffer from
 
I doubt there are many knives out there that will come close to the strength that the Tri-Ad lock has and that's in the production knives and they are pretty light for their size.

For Andrews customs, well they are at the top of the list IMO.

For the price it's really hard to beat a CS knife with the Tri-Ad lock, they make great user knives, strong and reliable.

I would say Spyderco's compression lock would be the more than strong enough also.

Saying 'really hard' would be an understatement , they are just impossible to beat at their price range in terms of strength

That being said , in terms of absolute strength , regardless of price and\or weight , I definitely believe Benchmade have the ability to make an AXIS which will be AT LEAST just as strong as Tri-ad , it's all about the components

I doubt the Axis lock could be made that strong, it's over complicated in design so the knife would have to be huge (HEAVY) to get that kind of strength out of it, it's a good lock, but it's not in the same league as the Tri-Ad.

That said a knife from a reputable maker that is designed well will serve well, just depends on what people want and like.

Settle down killer. Read a bit. The forces acting upon a compression lock are completely different than those acting on a liner lock, and in all reality a tri-ad lock has more in common with a compression lock than a liner lock does.

I think there's only one extra moving part compared to a tri-ad. All folders have a blade and pivot. Stop pin, lock bar, spring - that's on the tri-ad. Axis has that and a second spring. I think BM only made one linerless axis model, and some of the CS models don't have them, but I don't think liners really complicate mechanisms. And the tri-ad also has a second pivot pin for the lock bar.

1000 lbs at the pivot would translate to what at 4" from the pivot? I am curious but don't have the math.

250 lbs, 1000/4

if they tested one inch from the pivot. putting the load right above the pivot doesn't give a lever arm

It's hard for me to invision how they could actually improve on the Axis lock. I guess it they beefed up the springs and length of engagment along with increasing the lock pin size and the size/thickness of the liners, it could be stronger, and even more reliable. But it would become less user-friendly at that point too, I'd think.
 
OK, did I really just read more than one person talking about "necessary"? Like they were suggesting the things we buy are somehow controlled by necessity? Uh.... you realize where yer at, right? If we weren't going over "necessary" by 2000% on almost every knife decision we made, there wouldn't be a BF.

OP - this might sound really wack, but a lock type that gets commonly overlooked is the balisong. It is a very strong lock. As strong as the Tri-Ad? I dunno, but it's definitely a design to keep in mind if you like strong locks.

No, it won't be quite so easy as dividing by four.

http://en.wikipedia.org/wiki/Pound-force

It's really going to depend on the ratio of the distance from the force exerted to the pivot to the distance from the pivot to the device which is preventing the blade from closing (all things being the same).

someone should invent a knife for you guys, it would have to be large, very sharp great steel, and maybe ONE FRIGGIN SOLID PIECE TO BEGIN WITH!!! dumbass thread

I believe this has already been invented, so don't get your hopes up too high. It's called a fixed blade :)

he is talking about Spyderco testing, the rating is pretty simple, the load at one inch divided by the length of the blade. He was asking about the length along the handle, but it's the same idea to differentiate between light, medium, heavy, and very heavy duty (it may be a little higher depending on the knife, but the the handle is longer than the blade and VHD is at minimum 200 lbs per inch). They do this because the distances involved in lockbacks, liner lock, frame locks, compression locks, ball bearing locks, etc are all different, but they rate with one system.

Ah, I gotcha.

Probably should have slogged through the entire thread, rather than jump to the end.

If that's correct, an Espada would score 2400lbs at the pivot and still be competely functional... :eek:
 
I think we can all agree that the Spartan is probably the strongest folder for the price.:)

I think the X-large Espada is & the Rajah 2 is next. So I don't agree at all with that short ugly Spartan (am I the only one that thinks it looks like a peice of shite?) is the strongest. Appearances aside of course. :thumbdn:
