DEFINITION

Classification: 76/82

Miscellaneous devices and machines for sharpening cutters by removing the material of the cutter adjacent to the edge by cutting, filing, or chipping, as distinguished from abrading or swaging. There are a few patents for scissors-sharpeners, the action of which is somewhat analogous to swaging sharpeners.

(1) Note. See this class, subclass 82.2.
