Yep. The answer is right on it. It's a Yankee screwdriver. If the toolset
in the handle were complete, it would include a couple of screwdriver bits,
along with the drill bits. It supposedly would be used by people in the
wood crafts, like carpenters and cabinet makers. I have seen them in
collections, tool sales and flea markets, but I have never known of one
actually being used. As a screwdriver it's not too good, because the bit
tends to slip out of the slot as it spins, and when it does, the rest of the
stroke drives it into the wood.
