PRECISION SHARPENER FOR CERAMIC KNIFE BLADES

摘要

An electrically powered knife sharpener for ceramic (or other brittle, crystalline or amorphous media which could be used for blades) knives includes at least one pre-sharpening stage with a sharpening member(s) and includes a final stage with a sharpening member(s). There are one or more motor driven shafts on which the abrasive surfaced sharpening members, such as disks, are mounted. Guide structure is provided to guide the knife for aligning and positioning the knife facet precisely at a defined location on the abrasive surface of each rotating sharpening member. The pre-sharpening stage sharpening member(s) moves in a first direction. The final stage sharpening member(s) moves in a second direction which differs from the first direction.
