This is great. I'm glad to see BM start to show stuff like this.

I don't know if 600+ inch lbs. is a lot or not. It seems like a lot. It would be interesting to see that exact same test done on a bunch of different locks and/or knives.

it's quite good, but I had read something about 800 a few years ago. But the dimensions of the lock are not the same for all models. The failure of the liner lock is also not far off from a lot of other test claims.
 
Another reason to love the Axis lock. Although ease of closing is still why it and the Compression lock rate as two of my favorites. Arc lock, too, though it's a bit taboo to say so.
 
Now they need to stab a rack of beef ribs and poke holes in a car door, then have some fat guy go shoot a endangered rino. Good stuff I always had a feeling that the Axis Lock was one amazing lock system, but no really A knife is no good until you show me a vid of it stabbing some meat. I would love to see how some frame locks hold up to the same test.
 
I would like to know what that number translates to. 600 + inch pounds? Meaning 600 lbs per square inch?

I just wanna see them hang 600lbs off the back end and let it swing. A number that means something.

If the lock will hold 100 or 200 or 300 lbs at the lanyard hole, than that means something to me, because I know what the measurement means.

Any one have a translation?
 
Isn't that equal to around 50 ft/lbs? Maybe it's just me but it doesn't seem that impressive. Torque for a lug nut on a full size truck is around 150 ft/lbs and I can easily achieve this without much effort. The Benchmade fails at a third of that. That being said, I don't really put much thought into how much force it takes to make a lock fail when I am looking at a knife. In fact, I'm going to order a 300SN tonight.

it's torque, depending on handle length, the amount of torque from weight at the lanyard hole will differ, giving you inch pounds eliminates that

yeah, knife lock strength is not all that impressive to other tools, but locks generally don't need to be. That is why I like 'strong' locks, because none of them are all that strong anyway.
 
I sure wish they would make the Stryker model with the axis lock. The nitrous system is good but axis would be better in my opinion.

I agree. I hate assisted knives. The BM 910 was awesome. That was one of the first knives I owned. If they only made an Axis 910.
 
Reminds me of the Demko lock test. Pivot strength and testing at the lanyard hole. The ad-10 was over 800 and still functional, but test was different place and blade was much thicker. The Sog Vulcan arc says it can go over 1000, at pivot. I just like the axis because you never have to put your finger in the way to close and it is so easy to work.

inch-pounds is a measure of torque, similar to foot-pounds
pounds per square inch is a measure of pressure or stress

To figure out what 600 inch-pounds means you just have to do the math. If you figure that the lanyard hole is about 4 inches from the pivot, then divide 600 inch pounds by 4 inches and the result is 150 pounds, so you could hang 150 pounds from the lanyard hole.
 
nice video, glad to see benchmade did this , Just PLEASE PLEASE don't let them make a video in a few weeks of a fat guy in short shorts cutting rope, and slicing denim with meat stuffed inside, lol. The lock video was enough, I knew the axis was strong, thats all the proof I need.
 
I don't have that knife, but it looked to me like the distance from the pivot to the point of the press was roughly 2 inches. So that press would have been pushing down with 300 pounds of force.

In any event, the weakness wasn't the lock, but the stress points in the blade caused by the various holes and shapes and blade thicknesses.

I like this test because it shows that we don't really need locks stronger than the axis lock -- or probably the liner/frame locks, for that matter. To make locks and knives hold more force, you're most likely going to lose a lot of cutting performance for what is to 99.9 percent of us a meaningless improvement in breakage strength.

The axis lock is still my favorite lock.
 
In terms of lock security the Axis lock is definitely one of the best, but this test doesn't cover those aspects. Static loads are easy to demonstrate, but virtually no real world defeats are due to a slow, steady application of pressure in one direction. I like the Axis lock, Compression lock and Tri Ad lock for their overall design, not load bearing capability.
 
I've never seen a folding lock test where they test it to failure and the blade steel fails before the lock does. That's particularity impressive! But I agree, a static load test is only one of many indicators of a locks overall strength and in real world applications other forces come into play.

Still, it's nice to see that the lock does have some strength to it, not that I ever doubted it was a good lock for many reasons.

And yes, please no future vid's of them with a fat guy stabbing threw car hoods, dead pig's and meat filled denim pant legs!!!
