Hotmetal Ha! Love Tom’s suggestion of individual bean squashing vice! To me it looks more like it would be used for extracting confessions than coffee, an Acme Precision Truthmaster Pursuivant ™ thumb screw.
tompoland LOL @Hotmetal so if it’s about extracting confessions as opposed to extracting coffee, them maybe it’s more of a nut cracker than a bean crusher?
Pompeyexile Is it for breaking open coconuts or some other hard nut/fruit? Or what about pushing out a bearing?
Gagaryn The knurled knob is eccentric to the through bolt. The bright part looks like it has a sharpened face. It looks almost like some kind of lathe tool holder - albeit quite an agricultural one.
Gagaryn Close but no cigar. Hmm, some kind of architrave scriber or chamfering thingamajig? Definitely something for cutting or carving.
