I pretty much agree with hikermor on this. The thing is, it is not just the steel, but rather a combination of factors that go into a good knife blade. A given steel will behave differently if different heat treatments are used. Likewise, blade design factors in, in that some steels (and heat treatment) will work better with one design than another. There are infinite possible combinations, and every knife maker has their own secret sauce.

"Outdoor Gear Lab" has a nice article which discusses some of these issues. See The Hunt for the Best Pocket Knives. While the article is specifically about pocket knives, the discussion of steel, heat treatment, and blade design is applicable to fixed blades as well.

I have a large number of assorted knives kicking around the house. However, my EDC is a plain old ordinary Victorinix "Spartan", which costs about $25 at REI. It is on a very short lanyard with a Fenix E01 light, and rides comfortably in my pants pocket at all times. That knife and light gets more everyday use than all my other knives, multitools, and lights combined. Mostly because it is always with me.

The best knife steel is the blade you actually have with you when need it.
