Use this brush for cleaning the interlocking ceramic wheels on the Adjustable Edge Pro Electric Knife Sharpener (item # 50281) and the Ceramic Edge Pro Electric Knife Sharpener (item # 50245). The ceramic wheels will need to be cleaned twice annually, or more often if you sharpen regularly, to remove the buildup of the metal particles from the surface of the wheels. If you don't clean the wheels, their cutting capabilities could diminish. Use only this cleaning brush to clean the ceramic wheels.
