This invention is a manual sharpening device for knife blades that creates a micro-serrated edge on the cutting edge of a knife (microscopic saw). There are two types of knife blades on the world market: plain (flat cutting surface) and serrated (undulated cutting surface, also known as saw knives). Each has a wide range of shapes and sizes for various applications. This sharpening tool allows the user to create a cutting edge on any knife that combines the effects of the plain and serrated edge and thereby expands the potential applications of any knife.
