I don't know what the differences are, if any. I have read that they are about the same. I have several other knives in S35VN and they have all been great. I also already have a spanto in S35VN. I just wanted to try a different steel in the Spearpoint, that's all. Any of the steel Hinderer uses is good to go in my opinion.:thumbup:
I do know that 20CV used to be called Duratech 20CV. Now it's CPM20CV, I guess CPM bought out Duratech steel or something. I'm sure someone else on the forum knows what, if any differences there are and about the why it's now a CPM product.
Anyway hope your happy with yours. I am very satisfied with mine. I like the way this one fires open. Mine was put together by KJ and I think she must be the best assembler Hinderer has now. lol
