So,

Vanadium in amounts conducive to an effect on the steel are present in:

440V
420V
3V
10V
D2
BG-42
Vascowear
Wootz

Any other steels?

What do we know about vanadium and it's effect on steel?

Add W2, O1, M2, 50100B, Carbon-V, A-2, AUS-8, AUS-10, VG-10, L6. You may be overestimating how much vanadium it takes to improve a steel. Vanadium does not just increase the strength and hardness of a steel by the presence of the element and its carbides. The key for its usefulness in modest amounts is that it reduces the grain size in steel. Actually it retards grain growth.

Steels with small amounts of vanadium tend to take a finer edge. Classic examples of this are non-stainless O1 & A-2 or stainless AUS-8. Cutlery alloys without a little vanadium are a minority (counting types of alloys, not total knives produced). It's one of the reasons I disdain 440C and ATS-34.

What alloy was the 'chrome-vanadium' that Case use to use (evidently Case has said that they currently use 1095) ? I've seen a 6150 listed in some catalogs, evidently 61XX is a chrome-vanadium steel, but I've not heard of say 6180 or 6190 or such being used.
 
Case uses 1095 in their pocketknives? I always thought it was "surgical stainless" or something of that ilk. Is this not the case? Or do they have a special line with 1095?

Okay, here's my on-topic comment: Doesn't the V in Cold Steels's Carbon V stand for vanadium? If so, I guess you can add that to the list...

On one of the forums someone stated that the old Case "Chrome Vanadium" was just in the plating itself and that the bulk of the blade was 1095. I've got some of the older Case carving knives that are chrome plated. They seem easier to sharpen than old cheap chrome plated junk. It's hard to say whether there is vanadium in the primary alloy--well heat treated 1095 takes about as sharp an edge as anything. In the kitchen knife arena, Flint Cutlery used a chrome-plated blade with vanadium in the bulk alloy. They would get conspicously sharp.
 
Well, you can add to the list the "mystery steels" of the big brand-name kitchen cutlery, e.g., Henckels, Messermeister, Wusthof, Grohmann (which apparently uses the same German-made "high-carbon, chromium-molybdenum-vanadium steel" as the more prominent kitchen makers). Best that I have been able to determine, they all use something called "4/30" steel, I believe. Its composition resembles AUS8A, except that the content of its alloying elements appears slightly higher.

I haven't previously seen a reference to 61XX steels. Case used it? I'm NOT a knifemaker, but according to the UNS classification it is certainly a carbon steel; the "6" indicates that its primary alloying element is indeed "Chromium and Vanadium," and the "1" indicates that its presence is approximately 1% (w/the "XX" representing its carbon content...). Are there any other knives which use this steel? Hmm...
