Somebody, I forgot who, got his feelings hurt when the BFK broke.
I have tried to explain that having the same level of durability as the AKA 47, but with a narrower primary grinds and a higher hardness is impressive. We're pursuing edge retention and cutting performance too. But some people can't seem to understand that, so this video became necessary.
Making a knife that won't break is not rocket science. The standard BFK is more than durable enough for almost any practical use and it holds an edge well and cuts well. Edge retention probably far better than anything he has tested. But that isn't what he is evaluating. So I adjusted some geometry parameters to succeed with what he was evaluating, at the expense of cutting ability. The fact that it held an edge better than anything he has ever evaluated is just icing on the cake, and I think (or at least hope) people noticed that.
It was a very long video because he subjected that knife to much more than he normally does.
He actually did manage to chip off the very point, but not with just a normal amount of stabbing in a normal area.
He did manage to actually break the blade, but again not with a normal amount of rough use in that stump. He normally stabs the stump and pries it out. And a limiting factor is the torque that he can apply to the stump (actually it's a large log) without rolling the log over. And he ran against that limit.
I guarantee you there's never been a knife made that won't break if you put it in a large vise and put a sizable pipe cheater bar on it. Anything can be broken.
The tip break in the stump is usually limited to how far he can stab the blade into the wood and how much torque he can apply to it.
When it would not break under his normal process, he drove it in pretty far with a hammer and then started throwing the stone at it. It took a few tries but that did eventually do the trick. He expressed regret at doing that because it was outside of the normal process but he wanted to see what it would take, and we found out. He said "this is a survivor", but we'll see how many people notice that.
I wish, when he was shooting it, that he would have started with the 9mm because I know from experience that it is bulletproof with the smaller calibers, but anything will break if you shoot it with something big enough.
He shot the largest fragment with the 9mm repeatedly and seemed surprised that it shrugged it off without a mark but I would have been really surprised if it would have failed with just a 9mm.
