300 AXIS Flipper Lock Strength Test
Here is a video of Tracy and I putting the 300 AXIS Flipper lock to the test.

That's really awesome. I always thought the axis lock looked stronger than any other lock. Just the way it appears to me, something would have to completely break for it to fail. 0 -
Absolutely impressive! 0 -
Impressive stuff!
I'm curious how a 275 would do in that test, since it has both a heavier axis lock and a thicker blade... not that it really matters, since I'm never going to put anywhere near that much pressure on a knife anyway.0 -

The 275 is the strongest folder we've ever tested, with a lock strength averaging above 1500 in lbs of torque. It's ridiculously impressive.0 -
Very interesting. What I'd like to know is where all that movement comes from before the blade tang breaks. the back end of the handle looks to have dropped at least an inch and a half before the failure. something was stressing or getting misshapen up until that point and absorbing all that force, right?
makes me want to sell all my strykers

I knew there was a reason I liked my 300 it currently is my dedicated work knife too!!!

I'm really curios how a Hinderer/Strider/Sebenza would do in a test like that?
But then someone might claim that it's beneath their dignity to be sujected to such a crude test to the tune of "Hey, our knives are top of the line tools to be used and not abused, besides, you have our warranty".0 -

The Stryker failure was interesting. The lock liner "buckled" and completely blocked the blade; effectively turning the knife into a fixed blade. The blade didn't collapse (which could cause injury if in the hand). We then dissassembled the knife and simply replaced the lock liner. The knife was back to NIB condition!
So although the Stryker's lock isn't nearly as strong as the 300SN; when the liner buckles, the knife is still usable and completely repairable.0 -

So if I ever want to, say for example, lift a car with my knife blade, I should probably use my 275

I would like to see what a frame lock would do as well. I assume that it wouldn't buckle like the liner lock did (at least not so easily). I wouldn't think a Benchmade frame lock would be too much different from a Hinderer/Strider/Sebenza lock.0 -
Cool!
I tried to kill a 520T once and I maxed out the force gage I had at 500lbs and the lock still worked fine.
Now how about a 51 or 62?0 -

Interesting! I wasn't saying I wanted to sell them all because I was afraid of them breaking. I am not. Just that the axis lock is so very much stronger it seems like the most sensible thing to own. Of course I always knew that. When is an axis Stryker coming?0 -

and an Axis mini-AFCK? Mine has some Ti liners from the R&D dept, so I assume that makes the liner lock stronger than the steel ones that were standard, but still, an Axis lock so it would be fully ambidextrous would be best (I am a lefty, after all, and my mini-AFCK is a lefty model).0 -
Coolest job EVER! 0 -

We just tested the 755 MPR for comparison. The 755 averaged 519.6 in lbs of torque, and averaged -.3732” deflection distance.
The blade started to shear the lock bar face. The lock bar position moved and now permanently blocks the blade from closing but deformed enough to not stay in contact with the blade.
Here's a pic:0 -
wow. neato 0 -
Thanks for posting this test, Benchmade.
For the non-technical among us, can you explain the meaning of the "axis lock withstood 615 pounds of torque?" I.e., how much weight could you suspend on the lock before it fails?0 -
inch pounds.
Torque is measured a set distance from the fulcrum. The easiest thing to do is convert inch pounds to foot pounds.
Another pseudo test that would interest me would be a mechanically unsound method of applying force. For instance, my arms, slightly above average, will not apply uniform pressure to a blade, if I could easily generate those forces, given the 'wiggle factor' I would think that the lateral pressures would impact the total force required for failure.
Now I'm certain that this testing is above and beyond the applications that I subject my knives to. For fun it would be interesting to see what sorts of lateral force would need to be applied before causing failure and see if using wider washers would impact the lateral force required to cause failure.
A more reasonable test, I think, for blade performance would be CATRA testing, I'll sharpen whatever blades you want to whatever angle you want to pretty much any grit you want so we can watch the new M4 destroy the other steels. I'll even send in my 950-1201 for testing.
Seriously, I'll send in a waiver with my knife, free to test with cutting, no liability on Benchmades part... I think a mirror polished 20° inclusive edge would do the job nicely.0 -
Someone catch me...I think I may feignt! 
...all the years people have been screaming like idiots to see something like that...
To just see such a simple demonstration of test to failure now, is almost overwhelming.
Made my legs a little wobbly to see those two fine knives wrecked.When the 910 appeared I nearly cried out, No! Not that classic Stryker! hehehehehe!
Oh, somebody get me a cool rag, and a drink of something stout to clear my head!
Seriously though, wow...600+ ft pounds, wow.0 -

Cool! I hadn't thought about it shearing off like that, but I guess it isn't surprising.0 -
For you weirdo metric users, 58.3 joules. 0 -

You would take that 615 number and divide it by the distance in inches from the pivot. So say you want to hang a weight 2 inches from the pivot, you'd get 615/2=307.5 pounds could hang there. If you go out another inch it becomes 615/3=205 pounds could hang there.0 -
I'd be interested to see if the MPR did better with a carbonized lock face. 0 -
you guys ever see those "peg Boards" in high school you climb up using wooden sticks.
I bet we could use the 275 easily.
I wonder how a 710 would hold up in all blade materials and the same test.
Like how much force would each blade take before failure. barely noticable or 100's of pounds differences. say D-2 to M390 or an M4 blade0 -
Ok so now we need to make the 300 blade out of M4 and see the difference in the same test. Oh while your at it could you make a 3xx that has a blade length of 3.75" with M4? Thanks! 0 -
Thank you for sharing the video with us. 0 -
So I just had an idea. I'd like to see the strength of a knife like the 940 that does not have full liners. I imagine something could happen like the steel liner sheering off the screws and the aluminum that keep it in the scales. I'd love to know if it's significantly different in strength to full liner knives. 0 -
This video is just too cool. I've watched it half a dozen times now. Impressive! 0 -
I would like to nominate this thread and its included videos for an award of some kind.
Po has it right. We wanted to see this for years. Maybe not as many years as Po but just the same.
Thanks Benchmade!!!!!0 -
Sure beats CS test. 0
