I understand that there will always be discussion with differing view points - discussion is good, don't get me wrong for a moment. What I will say here, though, is that 55-57 RC is optimizing S30V for toughness. That's what this knife is all about - toughness. We have just tested a Green Beret blank that registed at 56RC - it chopped over 3,600 cuts into an old, weathered oak limb and still had an incredible edge. We have worked very closely with Crucible Steel to develop S30V, and we have all the resources of their research facilities at our disposal for scientific testing. From their results, my own experience, and our testing, I am convinced that 55-57RC is the optimium hardness for the Green Beret knife and for the CRK A2 one piece range. With the A2 one piece knives, we have 18 years of experience behind us, knives that have seen service all over the world and a tested track record. at 55-57 RC. Our knives are tough, they hold an edge, they perform.
