A nice Chip Chop mechanical ice chopper with a wood handle. It is marked Chip Chop & Pat Pend. It has 5 steel prongs & it works by spring action when pressing the handle up & down to chop ice cubes. It was made to chop or crush ice in an individual glass one cube at a time. The prongs are placed on the ice cube & the handle is pressed up & down to break/chop ice. It measures approximately 9-1/4 long & has a 1 diameter bottom. See photos for condition as it does show some corrosion on the prongs. Chip Chop Ice Chopper, Mechanical Cube Crusher For Glass
