We had a crucible failure one time in the forge and the molten copper ran into the ash dump forming a nasty mess of clinker, ash and copper.
I told the fellow working on it to use the *hack* saw and cut it up for remelting, turned around and he was using my *back*saw, one of my finest woodworking tools---totally ruined the edge of it and having it re-sharpened was going to cost several times what I originally paid for it...
I have also learned to put my "tool colour" on *everything* or else hold downs and punches and drifts get used as stock...
