The mystery object revealed to be a tobacco shredder.
You put a plug or small leaves of tobacco into one end of the cylinder, turn the handle and the sharp circular disc at the other end cuts it into shreds suitable for rolling your own cigarettes.

ATG note: thanks also to Kevin Peadon of Helm Antiques who pointed this out (adding it is a 19th century item).
