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.
Kyocera Product Information
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).
- 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.
- 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.
- 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.
- 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.
- 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.
- Each Kyocera knife comes with a five warranty. Call us at 800-537-0294.
- You can store your Kyocera ceramic knife in a conventional knife block, in an in-drawer tray, or in the package.
- 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 1000ø 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.
- 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.
- 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.
- We sandblast each logo onto the blade by hand.
- No, we do not.
- 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).
- 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.
- 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!
- The correct pronunciation is "KEE-OH-SAIR-RA," which comes from "Kyoto Ceramics," the original name of the company.
- 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!
- Kyocera annual sales are about $6 Billion worldwide.
- Yes. The shares are traded on the NYSE and listed under the KYO symbol.
- 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.
