Well as far as pants go, I normally cook in whatever pair of grungy shorts I have that I don't mind getting stuff on. When I think it will get messy I put my apron on. It reads "Bubba's Bar & Grill, Home of hot women and cold beer". I'f rom Alabama, what can I say.
I have a set of the one stickman Henckel's knives that work pretty well for me. My favorite knife for working with meat is a vintage Ontario Knife Co Old Hickory 10" slicing knife. It is high quality carbon steel, gets wicked sharp with a little work and holds an edge forever. I am looking at buying a new set of Ontario knives but they say the new ones are a good bit of work to get a good edge on the the first time, but easy to work with after that.
