Well, I do.  It's old.  It was my grandfather's.  
I don't know what it's intended for.  It's 2 lb., with a head that 
looks rectangular from the side, about 1 1/2" by 5".
from the top it looks more like a wedge.  One end is pointed, but not 
sharp, the other is somewhat rounded.

My best ever ASCII art :        '
  (for those of you who's inferior  mail readers don't have zoom capability, 
that's an apostrophie)

The catch is, the hole for the handle is an oval, only about 3/4 x 
1/2.  With such a small handle what's it for?  I have done some 
bashing with it, as if it's a sledge hammer, but that handle isn't 
likely to take much of that.  Or is it a wedge with a handle?

Knowing my  grandfather's interests is no help.  He was interested in 
everything.

TIA for any ideas.
