I would love some assistance in identifying this odd hammer that my daughter found in an old toolbox. See pics below.
It looks a bit like a sheet metal or riveting hammer, but I can't figure out the function of the split in one end and the open area behind it. The hammer is about 12 inches long...
I'm hoping to get some assistance identifying a very unusual old hammer. However, since I'm a new member, I'm not allowed to post pictures yet. Any suggestions as to what I can do?
