1st) Whatever manufacturer makes our stainless flatware in the kitchen
2nd) Chicago cutlery for the cheap block set in the kitchen
3rd) (Probably what you're really looking for) would be knives that I've made myself
4th) Tie between Leatherman, Victorinox, and Koster knives with two of each of those
5th) I have lots of other stuff from various makers and manufacturers but don't have more than one from anyone else that I can think of off the top of my head. I usually just get stuff that interests me or make stuff for myself.
For what it's worth, below is the first knife I made for myself. It's designed to be a small game skinning knife capable of working well in animals from squirrel to deer size, with an emphasis on animals from rabbit size thru 80lbs or so. I love it. I don't really make knives for a business, but rather as a hobby to give me a change of pace after work. It's a good way to relax and get my mind off things.
