does 3v hold an edge better than 20cv?

I got a survive 4.1 mainly for hunting in 3v because that was all that was available but im thinking I want to trade it for 20cv.

So what are the differences? I know 3v is super tough. Im not really gonna beat up on the knive that much. and i know 20cv has better rust resistance which i like. but what about holding an edge?
 
No, it will not. CPM 20CV is Crucibles answer to Bohler's M390, practically identical composition. So with 4% Vanadium 20CV will hold an edge longer than 3V.
 
CPM 3V

Carbon - 0.8%
Chromium - 7.5%
Vanadium - 2.75%
Molybdenum - 1.3%

CPM 20CV

Carbon - 1.90%
Chromium - 20.00%
Vanadium - 4.00%
Molybdenum - 1.00%
Manganese - 0.30%
Silicon - 0.30%
Tungsten - 0.60%
 
Guess i better look to trade or something. Edge retention and rust resistance is more important to me on a hunting knife

A bit about the steel used in SURVIVE! Knives:

CPM-3V is a high alloyed tool steel, made using the Crucible Particle Metallurgy process, that has a very high impact toughness and excellent edge holding. Being made with the CPM process, this steel is also very resistant to lateral stress (flex) breakage, making it a perfect choice for a high performance, hard use knife. CPM-3V is not a stainless alloy and can stain if not cared for.

CPM-20CV is a very high quality martensitic stainless steel, with outstanding corrosion resistance and excellent edge holding. CPM-20CV does lack the impact toughness of CPM-3V but being made with the CPM process, this steel is still very resistant to lateral stress (flex) breakage. Consider CPM-20CV for a very low maintenance, all weather cutting tool.

In those knives with that edge and blade geometry, the GSO 4.1 etc it won't matter what steel is chosen unless someone is going to be hammering the knives through granite... :D

I tested a 4.1 in M390 and I doubt one could hurt it..... It's that tough.....
