I once had a beautiful emrald green folding knife, only about the size of my thumb when folded. I used it for orange peeling and general bits and bobs. Anyways, I used to wear a cowboy hat at the time and being reletively young I thought it would be 'cool and what not' to keep it under my hat ala various Hollywood movie scenes. Safe to say the knife now lives somewhere along a 20 miles stretch of countryside between camps, I don't remember on which occasion it was but I had removed my hat a good three times before I remembered it was supposed to be keeping my knife safe.
