Well, I can give you a list of makers I personally think are among the best, with the understanding of course that there are knives from makers I havent yet seen. And like Keith, I could never limit it to 10, and I'm sure I'll forget some, but here goes. No particular order other than what pops into my mind first.
Tac/Utility, folders and fixed...
Mayo
Blackwood

Well, that's all I can think of right now, I'll add to the list if I remember others.
I'd be interested to see what makers others might add too.
OK, I'm going to try to pick my favorite 3 in each category, which is very tough and no matter how I choose, I'll feel like I'm leaving somebody out, but here goes...
