Lock Strength - Benchmade Bedlam vs Cold Steel Talwar

Finally...a fair fight.
I'd love to see the Buck Marksman Strap Lock and the Spyderco Compression lock tested... As well as the new thinner g-10 American Lawman.
 
I don't think the compression lock will do as well as people think. Its very strong for the size and weight of the knife but that thin little piece of steel will surely deform and fail with all that weight hanging from it. I saw a video of some Russians abusing the crap out of the para and the millie and the liner lock on the millie held up longer that the compression lock surprisingly. I think the pm2 would do well on the spine whacks though.
 
I would like to see that Buck Marksman tested though, I have yet to see any testing on that lock.
 
I would also love to see the BM 275 Adamas vs. a really built CS folder -- I'm not sure which has the strongest lock. I think the 275 is Benchmade's strongest, so it'd be cool to see it go against CS's strongest.
 
Hmm Adamas, yeah, but it's hard to find a CS that is in the same weight class and thickness.

Adamas:
7.7oz
~ 0.730inch handle, or ~1.85cm, which is the thickest handle i ever owned.
~ 4.5mm blade (the website said 4mm but it's more like 4.5mm, because i owned one)
~ 8.7inch overall, which makes it relatively thick and heavy for its length.

For a constant length, the strength of the knife is exponentially stronger as the thickness increases:

I can't find any CS production folder that is close to this dimension. The only thing with triad lock that is close to this is the Demko AD-10.
*hint hint, Cold Steel*

I think maybe a Mackinac Hunter-But it is no longer in production, so I doubt that it will ever make it into these tests.
 
Impressive but not a lab type of environment like the BM lab. It would be nice to know what the breaking point was on some of the CS steel knives.

BM's lab does provide a well controlled environment for accurate measurement of data, HOWEVER, their lab load test does not really reflect the real world scenario, because the load were increased in a snail crawling pace.
Also, from scientific standpoint, a "controlled" environment makes a lot of assumption that may not be applicable in real life scenario. There are always assumptions that certain factor has to be constant. Eg. Test the speed of the sound in the air, but sound moves faster in water and other medium. There are also variation between pressure, humidity, and you cannot assume the whole world has the same air density, pressure and humidity etc...
Look at all their load test videos, almost all of them were sped up 5-10x, if you play it in real time, it takes the machine forever to gradually apply force to reach the breaking point.
CS's load test has some impact element to it since the load was applied in a much faster manner(relative to BM's). Any knife(not just BM) will do much better better in BM's lab environment but may not do as well in CS's load test. Take a triad lock and put it on BM's machine and i'm sure it will generate a higher number.
