The Graef SG520 electric knife sharpener brings dull kitchen knives back to life. Its diamond-coated grinding wheels run slowly so the blade does not overheat, and the two-stage design with Dizor technology creates a curved, convex edge that stays sharp longer than a standard V-edge. A stable 20° sharpening angle and an elastomer blade guide let you guide the knife by the handle just as when cutting, so it is quick and easy even for beginners. The manual polishing stage also works on serrated knives.
