Well, CPM 20CV is an excellent knife steel. It's one of the best steels available for an EDC.
I like Vanax because it is not just stainless, but super stainless. That's an advantage because it means the newly sharpened edge doesn't degrade as much before use, caused in large part by oxidation. That oxidation can reduce sharpness by 20 BESS in the first couple hours, according to Vadim Kraichuk in his book, "Knife Deburring: Science behind the lasting razor edge."
Vanax is also tougher than most powder stainless steels, even Elmax -- Magnacut being the major exception. That toughness gives it better edge stability than most stainless steels. I use my Rukus 610 with a Vanax blade for chopping trail branches. It does much better than steels such as S30V and AUS8, and that's with a custom edge profile of 15 dps and a BTE width of 15 thousandths.
The other thing I really like is how fine grained the steel is. It's easy to sharpen to a high level of keenest. And it has excellent edge retention.
It's just a wonderful EDC steel.
