Sharpening

Sharpening is the process of creating or refining a sharp edge of appropriate shape on a tool or implement designed for cutting. Sharpening is done by grinding away material on the implement with an abrasive substance harder than the material of the implement, followed sometimes by processes to polish the sharp surface to increase smoothness and to correct small mechanical deformations without regrinding.

Famous quotes containing the word sharpening:

    Of course politics is an interesting and engrossing thing. It offers no immutable laws, nearly always prevaricates, but as far as blather and sharpening the mind go, it provides inexhaustible material.
    Anton Pavlovich Chekhov (1860–1904)
