How about a boot knife? This G-96/Jet-Aer Corp. No. 7003 I’ve had for 35ish years. It was a “gift” to me when I was in the Air Force. I was a Crew Chief on C-130’s in the late 80’s / early 90’s.
A tradition back in the day went something like this; any object (tools, personal items, equipment) left on the aircraft after a flight was considered F.O.D. (foreign object debris). If a Crew Chief encountered said object(s) they would be required to officially document the F.O.D. Or the object could be returned to the rightful owner unofficially for a fee. Usually a case of beer. Which would then be shared among the rest of the maintenance crew.
This knife came from a particular crew member that had a habit of leaving items behind on the aircraft. When I offered to return this knife he just sighed and said “keep it, I’m tired of buying you guys beer.” I did feel bad. A little bit. Because we had more than a few cases at his expense. So I did just offer it back sans ransom. But traditions back in the day meant something. He just said with a smile “It’s yours if I don’t have to answer for it.” He never did leave anything behind again that I can remember.
