I use a $4 folding "outdoor" pocket knife from Wal-Mart. I have used it for cooking, digging holes, cutting branches, rope, plastic, fabric, tightening screws, fixing zippers, opening cans of food, hammering random things... I honestly can't remember the last time I sharpened it, it doesn't seem to be dull yet.
