Rev:
You are not the only one who believes Case CV knives are plated, and this fairly common belief is partly why I asked. However, there is apparently "Chrome Vanadium Steel" which is not plated:
CHROME-VANADIUM STEELS. The vanadium content of this steel is approximately 0.181percent and the chromium content approximately 1.00 percent. Chrome vanadium steels when heat-treated have excellent properties such as strength, toughness, and resistance to wear and fatigue. A special grade of this steel in sheet form can be cold- formed into intricate shapes. It can be folded and flattened without signs of breaking or failure. Chrome-vanadium steel with medium high carbon content (SAE 6150) is used to make springs. Chrome-vanadium steel with high carbon content (SAE 6195) is used for ball and roller bearings.
According to AG Russell, you have to put at least 14% Chrome into steel to qualify it as "high carbon stainless," so the addition of chrome to Case CV may be to improve "strength, toughness, and resistance to wear and fatigue" over 1095.
If you can stick a CV blade into an apple and see results, it almost can't be plated. On the other hand, that guy at Case may have refered to other CV blades that actually are plated.
In any case, it sounds like a CV knife would be worth trying out.
