My mom bought mine somewhere I have no idea whereI carry the pilots knife every day to work. It's my ground knife, and general beater blade. I don't keep it very sharp. My main use is probing the ground, and cutting out sod plugs. It also marks position on the ground, and I use it hook a tape off to for measuring.
It was in 1985/86 I have it in my safe
Still great knives
Mine is a camillus iirc
