Definition

This class comprises special machines, processes, blanks, and dies for making tools, many of which are designated by the subclass titles, while the remainder are to be found in the proper miscellaneous subclasses.

The class includes mechanisms for sharpening various cutting-tools by the removal of the stock adjacent to the edge of the same by a cutting or filing action as distinguished from an abrading action. Mechanism for sharpening harrow-disks, etc., are included in this class because of their analogy to the other types of cutting sharpeners (see Subclass References to This Class, below).

This class also includes machines and processes for making dies, whether to be used as hand-operated implements or in forging or other machines.

General operation machines, though adapted by the substitution of special tool-forming dies to form tools, are classified in the general operation classes.
