On steels, I see each of the four majors differently.
D2. Tough as nails (surprising considering it's RC 59-60), nearly stainless. Used a Queen utility #11 for two yars at work, lots of corrosives around, and never got so much as a patina. Holds an edge excellently well and cuts very well, particularly when convexed. Hard to initially sharpen, but easy to maintain when you get it there.
Case Tru-Sharp. Easy to sharpen and purely stainless. Toughness is very high, owing to the low hardness (55-57). Edge can roll easily if the edge is too thin, reducing its cutting performance. Still acceptable if convexed and polished.
CV. I'd say it is 0176C. I've sharpened some Beckers and the like that are known to be and it behaves the same. Classic carbon steel, easily forms a patina. Touch harder to sharpen than 1095 at the same hardness, but just as good a user. Cuts great, takes a thin edge, holds it pretty well. Made to be convexed.
1095. Old reliable. Sharpens quick, takes a fine edge, holds it well. Stains easily, tendency to pit if used in corrosive environments.
So what would I take?
For edgeholding, it's D2. Stain resistance, Tru-Sharp. Ability to take a fine edge and hold it well? 1095 or CV.
