I don't know what else to call it. I have no idea what its purpose is. The business end is blunt -- it's not a chisel.
The head shows evidence of having 'mushroomed' from hard use, and the mushrooming having been ground away, so the thing has certainly been used quite a lot, for whatever it was used for. [I think that's what the English teachers call a 'run on' sentence.]
Anyway, should I ever discover that I need one of these, I'll have one; It'll be in the spare tools drawer.
