The Dexter EDGE-2 07921 hand-held sharpener has an overall length of 12 inches. It is easy to hold and safe to use. The user can hold the sharpener with either hand. A new edge is created since the diamond sharpening stones shave metal off the edge of the blade. If the blade looks scratched or rough, it can be polished with the white ceramic polishing stones on the Dexter EDGE-2 07921 hand-held sharpener.
