If I had a Diamond Blades knife I would hit a rock with it in full, as I did with my Skinny ASH, with my Bushman and many others to see what happens. If that 65-68 HRC edge would not chip while hitting the rock that way, then I would declare it tougher than INFI and than anything else I've ever tested. And then I will replace my Skinny ASH in my kit with one of their knives if they make a bigger one.

But I can't risk so much money just to test that; if I do that relying just on manufacturer's claims and theory, I have chances to end up as I did with my Fallkniven A2 which I thought it's much tougher than it really is. So I hope I will see some day somebody else doing some hard use tests against a Diamond Blades knife. Until then, there are not enough practical prove to have a real opinion about how tough these knives are.
