Knife, twice. Discovered it when I was leaving camp, so grabbed a (ghitsu) knife that was in the camper. Shot a decent 4x5 Muley, and boned the whole deer out with that cheap serrated ghitsu. It was long, but worked ok. 2nd instance was when I discovered I only had a cheap multi tool after downing a bull 3 miles from the truck. Ended up boning that out with a dull blade.
