Imagine a knife which goes months, even years, without sharpening. Kyocera Ceramic Knives and Gadgets are a unique alternative to metal-based products.
Kyocera utilise zirconium oxide, aluminium oxide and other advanced ceramics to create products which combine elegance and strength.
Kyocera ceramic products are perfect for general applications requiring superior edge retention and wear resistance.

Ceramic Vs Metal

 

A forged metal blade is soft and susceptible to chemical corrosion. Over time its edge "rolls" and "pits"





Kyoceras zirconium oxide blade resists the wear and holds its edge for months without sharpening.

Kyocera Ceramic knives are made of an advanced, high tech ceramic called zirconia. This material, which is second in hardness only to diamond, was originally developed for industrial applications where metal components failed. Zirconium oxide is extremely hard, wear resitant and chemically inert. For the technically minded, zirconium oxide has a hardness of 8.2mohs. (vs. steel at 5-6mohs and diamond at 10mohs)

You can sharpen your ceramic knife by using a diamond sharpener or a professional sharpening service.

Any knife, whether stainless steel or ceramic, will potentially break at the tip if its dropped on a hard surface at a certain angle. Unfortunately accidental damage can occur, most minor tip breaks can be fixed by re-sharpening your knife.

Do not use as a pry or a lever.
Do not use to cut through bones.
Do not use as a chopper.
Use only on a wooden or plastic chopping board.

We do not recommend this for several reasons. First, it`s dangerous if someone forgets about the knife or reaches the wrong way. Second, violent motion against other objects, especially hard plates, could chip the objects and/or the knife. Third, dishwashers ruin wood handles. Finally, ceramic knives are very easy to clean with a hand washing or mild bleach solution..

All kyocera knives come with a five year limited warranty.

You can store your Kyocera ceramic knife in a conventional knife block, an in-drawer tray, or in the package.

Kyocera produces ceramic knives in Sensai, a small city in southwest Japan on the Island of Kyushu.

First, Kyocera mould ceramic powder into blade "blanks" using special high presure (many tons!) presses. Special binders in the powder allow the blanks to retain there shape before sintering (or firing), which takes several days at extremely high temperatures (in excess of 1000°c). Kyocera then grind (on a diamond wheel) and polish the sintered blanks to form an edge and the final shape before attaching the handle.

Kyocera Ceramic Knives work best for slicing boneless meats, fruits and vegetables. Avoid flexing or prying. Use with a plastic or wood cutting board. Avoid cutting on marble or stone or inappropriate surfaces like plates or kitchen tile.

A black (HIP) blade is made out of a black zirconium oxide and offers extra durability. This type of blade goes thorugh an extra firing proces called a "hot-isostatic press," creating a tighter weave between the ceramic molecules, thus creating a tougher blade.

The correct pronunciation is "KEE_OH_SAI_RA," which comes from "Kyoto ceramics," the original name of the company.
