My father in law has this tool that was handed down to him. He doesn't know what it is, nor do I. It looks old but who knows. The dial says "patent applied for" but there is no other reference numbers anywhere other than the numbers on the dial. The shaft has a chisel point to it, so when its held into something and the "key" handle is turned, the dial rotates to indicate the change in the face of the dial. Any ideas?
