I dont personally own one, but one like it.. The Ka-Bar USMC knife is one of the best all around knifes i think. It may be a little big but even on little trips, i have my hunting knife which is similar, and a small knife. If you go to an army-navy store, they sell "survival" knifes with the screw off caps and store stuff inside. I'm intending to get one soon so i'll let you know how that works out.
