Am I missing out on some steels? Steel talk.

A previous quote from Larrin.... "Personally I would probably prefer K390, 10V, or Vanadis 8, and those steels can also be heat treated to 66+ Rc if desired. S390 and other high speed steels are not as optimized"

It's edge retention is around k390, but less tough than A11/10v

I had K390 microchip on me if I'd twist the blade while it's biting into the wood, it happened on both, Endura and Endela, and the same didn't happen to S390 even at way worse abuse. This difference could be due to various factors I forgot to take in consideration, but that is my personal experience with those 2 steels.

Only experience I have is sharpening a k390 knife.
It was Very dull. And was very difficult to get sharp again. I was forced to buy a diamond stone.
I'm a better sharpener now, so id like to try a knife with it.

I've got a couple 10v blanks out for hardening, so someday I'll have those too, to play with
 
A bunch of Eropean pocket knife makers use C75, XC75 and XC90. Could be mostly because of the blade profile, but no Case or Buck pocket knive can reach sharpnes/cutting ability(?) of the slipjoints made from the above mentioned steels if sharpened by me. My post is more a question -are these steels better for reaching very sharp edge compared with other inexpensive carbon steels if everything else is equal?
