Kirko, I'd use that AUS-8 blade that you posted the picture of without any worry whatsoever. AUS-8 is a good steel for a good price. Especially in that case, since it was a gift. IME, AUS-8 takes a wicked edge, holds it a LONG time (as long as most of the "super" steels that I have used), and is easier to sharpen when it does get dull. It is, along with a few others, at the peak of the compromise curve, in my opinion. With only ONE exception that I have found, the longer a steel HOLDS its edge, the harder it is to get it back to that edge once dulled (and EVERY steel will dull eventually). My preference is a steel that holds its edge well as long as I'm careful with it, and is rather easy to sharpen once it is dull. AUS-8 does that, in my experience. Quite well.
