Bahco/Snap-on ratcheting screwdrivers?
 

Stubby...
Bahco 808050S
Bahco 808050TS
For less than $20 (USA) on eBay and Amazon.

Weird IMO that those do not mention the removable shaft. But
apparently it is, since the combination set (Bahco 808050S-22)
includes the 808050S.

Trying to find out what sort of connector the shaft uses (and to
verify that in fact the shaft is removable). I guess it's a standard
1/4 inch square with a ball locking mechanism.
