Case CV(Crucible) - As some other proprietary names, Case Chrome Vanadium(or Case CV) is just the name for any given alloy used currently in Case knives. Similar story with Cold Steel Carbon V. Unfortunately, they don't exactly announce when the steel changes. Until late 90s, or perhaps even mid 2000 Case CV was based on AISI 1095 carbon steel, and later on, it has been changed to AISI 1086 steel, with trace amounts of Vanadium and Chromium. According to knifemaker Don Hanson III's tests it's 0.50% Chromium and ~0.20% Vanadium. Not nearly enough to affect wear resistance or rust resistance, but will help with grain refinement. Overall, those two alloys (1086 and 1095) are quite close and heat treatment of the steel is much more important than the difference in composition. Older Case knives were about 5-10 RC points softer compared to current line, which isn't hard by any standards either - 55HRC or so.
