Kyocera Product Information

Why choose ceramic knives? Why not? Imagine knives and scissors which go months to years without sharpening. Imagine ballpoint pens which don't flatten or skip, and produce the ultimate in smooth writing. Kyocera Ceramic Application Products are a unique alternative to metal-based products.

They utilize zirconium oxide, aluminum oxide, and other advanced ceramics to create products which combine elegance and strength.

Their ceramic products are perfect for general applications requiring superior edge retention or wear resistance. They are also ideal for special applications requiring chemically inert, non-magnetic, non-conductive, or non-contaminating materials.

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

Kyocera's zirconium oxide blade resists this wear and holds its edge for months to years without sharpening.

What are ceramic knives made of?
    These knives are made of an advanced, high-tech ceramic called zirconium oxide (also 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 8.2 mohs (vs. steel at 5-6 mohs and diamond at 10 mohs).
How do I sharpen ceramic knives?
    You can resharpen your ceramic knife by sending it back to us or by bringing it to a qualified knife shop which has a powered diamond sharpening wheel.
Will a ceramic knife break or shatter if I drop it?
    No (with the possible exception of the tip). Zirconium oxide is a very strong material. Like a forged steel knife, however, you can break the tip if the knife lands on the tip. Fortunately, we can repair most damaged tips under the five year warranty.
How can I damage a ceramic knife?
    Two ways. First, you can chip the edge if you cut into bones. Second, you can break off the tip or snap off the handle if you use it to pry.
Can I put my ceramic knife in the dishwasher?
    We do not recommend this for several reasons. First, it's dangerous if someone forgets about the knife or reaches in 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 quick wipe since food does not stick to the blade.
Why are ceramic knives so expensive?
    Two reasons. First, zirconium oxide is a relatively new, advanced material which costs more than steel. Second, the U.S. government charges an unusually high import duty on advanced ceramic products.
Do Kyocera knives come with a warranty?
    Each Kyocera knife comes with a five warranty. Call us at 800-537-0294.
Where should I store my Kyocera ceramic knife?
    You can store your Kyocera ceramic knife in a conventional knife block, in an in-drawer tray, or in the package.
Where are Kyocera knives made?
    Kyocera produces ceramic knives in Sendai, a small city in southwest Japan on the island of Kyushu.
    First, we mold 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). We then grind (on a diamond wheel) and polish the sintered blanks to form an edge and the final shape before attaching the handle.
Which Kyocera knife is sharpest?
    The KC-130 and the KC-200 are our sharpest knives. Most Kyocera ceramic knives have an edge formed by one vertical side and one angled side. The KC-130 and the KC-200 have edges formed by two angled sides.
Why is the black knife, the KC-200, black?
    The KC-200 has a special blade made of zirconium carbide, which turns black when fired. Zirconium carbide is even more resistant to damage from misuse or dropping.
How do you make that neat Kyocera logo right into the blade of the wood handled knives?
    We sandblast each logo onto the blade by hand.
Do you sell direct to the public?
    No, we do not.
What new models are you planning?
    We are currently developing on a 3.5" Paring knife, a 4.5" wood-handled Fruit Knife (our current model, the LK-35, has a plastic handle), and a Bow Style Peeler (our current model peeler is a Yoke or European style).
Do you make ceramic scissors as well?
    The most recent product introduced in the market is a 6.0" inch serrated blade knife. Our next project is a mandolin slicer with a ceramic blade.
The peeler is great! How come you don't make a shaver?
    Too dangerous! A metal razor blade has a relatively "rounded" edge (under the microscope) which prevents the blade from cutting into the skin. A ceramic razor blade, however, does not have a rounded edge and slices into the skin. Thus, a ceramic shaver would be too dangerous to use. Several engineers in Sendai who tested prototypes can confirm this painful fact!
How do I say "Kyocera" correctly?
    The correct pronunciation is "KEE-OH-SAIR-RA," which comes from "Kyoto Ceramics," the original name of the company.
What else does Kyocera make?
    Kyocera is one of the world's leaders in advanced ceramics and electronics. We manufacture a wide variety of products including semiconductor packages, capacitors, thermal print heads, resistors, cutting tool inserts, circuit substrates, LCD panels, fiber optic components, car engine components, solar modules, cameras, laser printers, wielding nozzles, cellular/PHS phones, pump components, synthetic gemstones, thread and wire guides, antenna mounts, and lots of other neat stuff!
How big is the company?
    Kyocera annual sales are about $6 Billion worldwide.
Is it a public company?
    Yes. The shares are traded on the NYSE and listed under the KYO symbol.
Does Kyocera have offices or production in the U.S.?
    You bet! Kyocera has four subsidiaries in the U.S. which employ several thousand Americans. Although the world headquarters is in Kyoto, Japan, Kyocera has production facilities in the U.S., Brazil, Mexico, Ireland, England, the Czech Republic, Guatemala, France, Israel, China, and Japan. The U.S. subsidiaries are based in San Diego, Vancouver (WA), Somerset (NJ), Myrtle Beach and maintain sales offices throughout the U.S.
