One item not mentioned (I've gotta log in more often) is a wonderful substance called Renaissance Wax. I have gathered any number of knives over the years, along with a few real (as opposed to costume or wall-hangers) swords. Ren Wax goes on easy and comes off with a wipe, but it is a preservative so I wouldn't consider it for food preparation material unless you know you will have a chance to really wash the contact surface first. I'm thinking for a BOB or just preservation of metal not presently in use. I'd offer a link, but anyone can Goggle it and probably find a cheaper source. One can lasts a while.
