Kyocera Ceramic Knives F.A.Q.
Why should I choose a Kyocera Ceramic product?
Imagine a knife which goes months, even years, without sharpening. Kyocera ceramic knives and accessories 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.
Why should I use a ceramic and not a metal blade?
A forged metal blade is soft and susceptible to chemical corrosion. Over time its edge "rolls" and "pits". Kyocera zirconium oxide ceramic blades resists the wear and holds its edge for months without sharpening.
What are Kyocera ceramic knives made of?
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 resistant and chemically inert. For the technically minded, zirconium oxide has a hardness of 8.2mohs. (vs. steel at 5-6mohs and diamond at 10mohs).
How do I sharpen a Kyocera ceramic knife?
You can sharpen your ceramic knife by using a diamond sharpener or a professional sharpening service.
Will a Kyocera ceramic knife break if I drop it?
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.

Can I put a Kyocera ceramic knife in the dishwasher?
No, 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 by hand washing.

Kyocera produces ceramic knives in Sensai, a small city in southwest Japan on the Island of Kyushu.
How are Kyocera ceramic knives made?
First, Kyocera mould ceramic powder into blade "blanks" using special high pressure (many tons!) presses. Special binders in the powder allow the blanks to retain their 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.
How should I use my Kyocera Knife?
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.
What is the difference between the three ranges of Kyocera ceramic knives?
Kyocera FK Anthracite black knives contain carbon and are 30% stronger and therefore sharper than Kyocera FK Zirconia white knives. Kyocera KYOTOP Sandgarden knives go through an extra firing process called a "hot-isostatic press," creating a tighter weave between the ceramic molecules, resulting in an even harder and sharper blade again.
How do I say Kyocera correctly?
The correct pronunciation is "KEE_OH_SAI_RA," which comes from "Kyoto ceramics," the original name of the company.
