Man their are tons of on-line places & articles to find info on knives, best bet is do a google search or check out what the other guys have posted - that's good stuff.
I have quite a few knives but the one that finds it's way into my pocket most often is my Case Stockman 3 blade pocket knife.
A gift from my wife... she liked the color - I just liked the knife.
Perhaps I'm just a bit old school but IMHO you just can't beat a folding pocket knife for everyday use. This one is of good quality and not too expensive so if anything happened to it, I'm not out a ton of $$$ here.
Good luck and have fun shopping.
