I have a pouch sheath strapped to my bag that is dedicated to (at least) a Tinker Deluxe and usually a Swiss Champ. I'd have to say that an SAK gets more use than any other EDC (and I use my knives a lot). Yes, I carry other knives in addition, but it's the SAK that sees more work time. No, not glamorous "he man" stuff, but the necessary aspects of a fairly physical lifestyle.
