I watched the Yankee drivers being used by tradesmen as I grew up ... along with the 'eggbeater' drill, the 'brace and bit,' and a few other tools you don't see anymore.
Indeed, I just added a 'medium' Yankee to my tool bag for trim-out work.
The shortest spiral driver isn't very practical. To be effective, you need LENGTH. Torque depends a lot on your being able to press on it, and the longer the travel, the better. I've used them, with great effect, for driving screws into wood (pine and oak).
Ones that use "normal" 1/4" hex drive bits? Where? I'd love to get one .... if there were ever a tool made for the Robertson drive, this is it!
