OK, nothing I didn't know about. Thanks.

Pump action screwdrivers were very common in TV etc set construction.
When
the BBC changed from slotted to Pozidriv screws in the '60s, accidental

I certainly bought mine for scenery building - at university.

I use my screwdrivers as much for undoing screws as doing them up. Yankee
is no good for undoing.
