Here’s a rare retro tool oddity from the swingin’ 70’s…the aptly named Screwball! 
I know ratcheting screwdrivers aren’t exactly that unique or unusual but the name "Screwball" just begs for attention.
Approximately 30 tooth ratcheting screwdriver with a roughly 2” diameter handle. Handle has both a red and yellow colored hemisphere (overall, it looks like a fishing bobber). The handle feels ergonomic and comfortable – using the Screwball feels much like operating a standard household door handle. The shaft is aluminum with a strong magnetic bit holder. I only have one original standard bit but modern ¼” bits fit nicely as well. Integrated into the handle are three bit compartments enclosed by a clear plastic component which can be rotated about the shaft to reveal/store bits. The blue switch is a forward/reverse selector and can also be aligned directly in the middle to lock the shaft and disable the ratcheting feature to enable use as a non-ratcheting driver.

Hard to see in pics but handle reads:
“SCREWBALL
Pat
Pend
RATCHET
DRIVER
USA
S/V Tool Co."
I've never heard of the company S/V elsewhere. I also found out that there’s an ad for it in the 1978 May issue of Popular Mechanics which can be found in Google books. Looks like it was a Ronco product. I don't know if that's a good or bad thing. Here’s a direct link to it:

Enjoy.
