RE: A really good knife.....
I've been looking too, but with little luck. Being the kind of person who is very picky about knives, I've decided to make my own. I've only been reading about it to this point, but already have the tools to do it with (it doesn't really require much). Brucelanthier is right; it is the steel, not how new it is. Good steel will hold a very sharpe edge for a while. I have a custom knife that was made for my father. I have no idea what kind of steel it is, but it's edge will last an entire season (approx 6 deer). But it only cuts deer. I carry a cheap knife also for cuting stuff that could and would dull the blade, one that I can resharpen easily on a curb if I decide, or replace it for $15.
I'll let you know howmy knife making goes, and you can make one too if you're interested. I think it would be cool to pass some home-made custom knives down to my children one day, but they'd have to be nice.
I can send you some links on the topic if you like.
