I'm going for the blacksmithing tool myself.  Especially something 
you would strike with another hammer.  This one doesn't show signs of 
that, but maybe it was used by my grandfather for something else.  
Kinda like some of the flea market iron I drag home and use for 
whatever I need at the moment.

My own guess is Esther was right (again)
