Kyocera Innovation Black 7-inch Ceramic Chef's Knife

The 7-inch chef’s knife is the longest Innovation Black knife we carry and the one to reach for when the board is full. Its length covers a whole head of romaine or a row of carrots in one stroke, and the pointed tip handles the fine mincing of garlic and herbs. Kyocera describes it as the most commonly used knife shape in professional and home kitchens.

On produce, ceramic has real advantages. It does not react with acids or rust, and Kyocera rates the edge at double the working life of its earlier ceramic. Bones, frozen blocks and prying will chip the edge, so pair it with a steel knife for those jobs.

Our answer, when someone asks how a ceramic chef’s knife gets sharpened, is diamond. The Kyocera RSD-01 diamond sharpener restores the edge at home. EVERSHARP, the repair service Kyocera authorizes, takes care of heavy wear and chips; Kyocera’s sharpening service page has the form.


Choosing a Larger Innovation Black Knife

The 6-inch Chef’s Santoku has a flat edge for push cutting and is a little shorter. This chef’s knife leads the Innovation Black 4-Piece Set, and the Innovation White 7-inch Chef’s Knife is the white-blade version.

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.

Wash by hand with warm, soapy water and dry right away. Kyocera advises keeping its knives out of the dishwasher because handles can warp over time; if one does go in, use the top rack only. 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 7-inch Edge Guard.


Warranty

Kyocera’s limited warranty covers its knives only when they are bought from an authorized Kyocera reseller, and Knife Merchant is one. For purchases made after July 13, 2023, coverage runs one year from delivery and excludes misuse and accidental damage.
