Abstract
This invention relates to knife sharpeners, and particularly to knife sharpeners of a kind which are incorporated in a holder for the knife in which the knife is placed when not in use. In such holders the blade sharpener is located so that the action of positioning the knife in the holder, and/or the action of withdrawing the knife from the holder, moves the cutting edge relative to the sharpening device to effect a sharpening action. The knife sharpener of the present invention is provided with means which are incorporated in the holder for varying the effectiveness of the sharpening device even to the extent of rendering it inoperative.
