Most people have seen the Yankee spiral ratcheting screwdrivers, and many of us here own them. Yankee/North Bros. also made drills. This eggbeater is a no.1530A, has a 5-position transmission with ratchet either direction featured. But recently I came across this large wood handled screwdriver. Fourteen inches overall, with the name on the ferrule, also has a knurled ring at the bottom of the ferrule. Yankee also made a very good brace drill, with a unique ratchet. Anyone else have a plain screwdriver?
