Informative input to this point. I was hoping for something definitive, and it
may come along.
The things that stand out to me are the hard rubber handle, the pin through the
middle that seems to be intended to keep it from rolling, the blade end not
being sharp, and that the ends are screwed in. I truly have no idea what the
tool was designed for, and several logical things have been suggested, though
none seem to be a dead on match.

Any further input is appreciated, and any definitive identification much
appreciated. I would not be surprised if  it matches one of the things suggested
to this point, but I would really like a solid ID if I can get it.
