I think this may be a leatherworking or possibly woodworking tool. Can
someone ID it for sure, please?

I looked and have no idea, but calling it "a tool" may
also be misleading. It looks as if it could have been
a lever for some larger apparatus too. Also was curious
about the scrap of leather attached to the wooden handle?
