Not sure where you're at, but Steven's Creek Surplus which I think is in Santa Clara has the biggest selection of knives I've seen, which isn't saying much since a decent knife shop is hard to find around here. Also, WeBeKnives on Pier 39 is supposed to have a decent selection but very high prices. Their people are really knowledgeable and they are willing to order anything. I think there's another one, Sonoma Cutlery which is supposed to be pretty good. Redwood Surplus in Redwood City sells a lot of tactical and bush knives, like TOPS, Benchmade, etc. The knife guy that works there is a knife nut and he can steer you in the right direction, too. All these places have websites, so you might want to look at those first. Good luck.
