Staedtler 502 Lead Pointer Tub Sharpener

The Staedtler 502 lead pointer tub is a rotary sharpener for 2mm leads.
Two automatic settings for sharp or blunt leads - set the lead depth in one of the two holes, insert pencil into sharpener hole and rotate the whole lid using the pencil as a crank, whilst holding the canister.
Sharpening automatically ceases when the lead is pointed.
It also features a foam insert for cleaning dust from the lead tip.
Designed for use with Staedtler's 2mm clutch pencils. Will work with some others, but pencils from other brands may not fit.
A solidly-made item that should last for years.
