Support BladeForums! Paid memberships don't see ads! I think if CRK ever switched to anything it would be 20CV. I don't see them moving "up" in the S series of CPM steels. They just don't have the balanced trait that I think CRK feels they have in S35VN (and I agree). 20CV has the ability to offer that balanced factor, if heat treated well. It could do very well in the CRK lineup, but I'm not holding my breath. Nor am I at all unsatisfied with CRK S35VN at 59-60RC.
