It seems you're a Cold Steel fan. You mention Carbon V...this is where you need to do your homework. Like Cold Steel's "San Mai III," Carbon V isn't a specific steel or alloy either. Cold Steel's marketing isn't a reflection of the quality of the knives and you'll find many positive comments about Carbon V knives. You should take a look at zknives.com. There is a ton of information there...

Carbon V
Carbon V is a trademarked term by Cold Steel, and as such is not necessarily one particular kind of steel; rather, it describes whatever steel Cold Steel happens to be using, and there is an indication they do change steels from time to time. Carbon V performs roughly between 1095-ish and O1-ish, in my opinion, and rusts like O1 as well. I've heard rumors that Carbon V is O1 (which I think is unlikely) or 1095. Numerous industry insiders insist it is 0170-6. Some spark tests done by a rec.knives reader seem to point the finger at 50100-B. Since 50100-B and 0170-6 are the same steel (see below), this is likely the current Carbon V.
