Abstract
A razor blade sharpener utilising the principles of an electrochemical cell. The blade (10) forms an anode (−) and a cathodic plate (16) is provided in close proximity to the razor edge (12) to be sharpened. The present invention electrochemically sharpens the edge (12) of the blade tip (14) to provide a fresh, or “as new” razor blade.The blade sharpener has additional uses for sharpening, for example, kitchen knifes and surgical blades.
