This early 20th century hand-cranked sharpening device was manufactured by the Luther Grinder Manufacturing Company of Milwaukee, Wisconsin, U.S.A.
Dating from around 1908–1920, the machine features exposed cast iron gears, chain-driven mechanical movement, and a hand crank operated sharpening system.
Designed before modern electric sharpeners became common, machines like this relied entirely on manual power and clever engineering. The gearing system allowed for smooth dual-direction sharpening, helping create a more even edge on tools.
A fascinating example of practical industrial design from over 100 years ago.
