Care

Cut on a wood or plastic board. Marble, stone, glass, tile and plates will chip a ceramic edge. Kyocera recommends a steel knife for carving, boning, prying, frozen food and cheese, and advises against flexing the blade or twisting it in the cut.

Kyocera rates Innovation White knives as dishwasher safe and says they can be sanitized in a mild bleach solution. In the dishwasher, use the top rack, as Kyocera advises for its plastic-handled knives. If the white blade picks up stains from foods such as beets or turmeric, Kyocera suggests a paste of baking soda and water. A ceramic blade can break if dropped on a hard floor, so store it in a block such as the Kyocera Universal Knife Block or in a Kyocera 4.5-inch Edge Guard.

Sharpening

A ceramic edge can only be sharpened with diamond abrasive. Ceramic rods and ceramic-wheel sharpeners, including the Kyocera Ceramic Wheel Sharpener, are made for steel knives. For touch-ups at home, use the Kyocera Diamond Wheel Sharpener. For a dull edge or a chip, Kyocera’s authorized service provider, EVERSHARP, sharpens Kyocera ceramic knives and grinds out chips; the request form is on Kyocera’s sharpening service page.
