Was at a get together Labor Day weekend and a friend had a tool he'd found in a box of tools from a sale. He (in his 60's) said his father had one when he was a boy but it was the only other one he'd seen. No knew for sure what it was but we all had ideas. Mine seemed to be the most plausible by everyone's guess...I thought you'd wrap emery paper around the tool locking it with the thumb screws for a small contour sander.
