RE: CV and Carbon V,
According to the afore-mentioned article from AG Russell's knife encyclopedia, and also according to Mike Stewart (of Black Jack, Marbles and Bark River), 0170-6 AKA 50100-B was used by a number of makers, most notably Case (under the name Chrome Vanadium) and Cold Steel (as Carbon V.) But some suspect Cold Steel also marketed other steels as Carbon V.
Here is a link provided by SodBuster, in an earlier thread. See post #11

Caveat: I don't know STR, nor can I vouch for this being an authentic quotation from Stewart.
Gee, three different applications so three different steels would be best for each.
Yeah, that's what I'm asking. JShirley said it would depend, so I'm giving three different types of knives, and asking for the best blade steel for each different type.
But I'm not sure I really understood what he was saying, because later he posted:
You've really got to think of your priorities. Do you need your knife to be easily resharpenable on almost anything, for example? If so, your steel choice might not be a "super steel" that holds an edge quite so long.
Well, if that's what you meant, John, that's not something I think about. The idea of a sharpening a knife on any old rock has never seemed realistic to me, even though I've heard it discussed quite a bit, and some survival instructors even told us which type of rock to use (Of course, by now I've forgotten what they said.) Maybe I'll look to see if there any threads on that topic, to explain what that's all about.
Edit: I'm not sayin' there's anything wrong with improvised sharpeners, I'm just saying that I didn't have that consideration in mind.
