What is special about Kyocera ceramic knives?
The light weight zirconia blades are extremely sharp and they maintain this sharpness considerably longer than other blades.
The ceramic surface of the blade is smoother than a steel blade allowing it to cut through any food effortlessly. The knives are made of a hygienic material which is neutral to taste and corrosion free.

Which material is the Kyocera ceramic blade made of?
This ceramic cutlery is made of qualitative high-grade Zirconia ceramic. This material is fired at a temperature of 1500°C (technical term: sintering) and at a pressure up to 20.000 t/sqm (HIP-procedure).
This basic material does find application in aerospace, automotive industry
and medical technology.

What is reccommendable for usage and maintenance?
Ceramic knives are low maintenance and easy to clean. High-quality knives should always be cleaned by hand, not in dishwashers. It is recommended that the knives be used on a wooden or plastic chopping board as the ceramic is extremely hard and therefore less flexible than metal blades.

Please follow the following instructions to avoid chipping or breaking the blade:
• Do not drop the knife as this can cause the blade to break.
• Do not use the knife for plaining or grating
• Do not use the knife as a lever
• Do not twist the knife during the cutting process
• Do not use to cut frozen goods, bones or fishbones

If the tip does break off it may be possible for the knife to be repaired.

Is it possible to get the ceramic knife re-sharpened?
In principle yes, although this happens very rarely. However there is appropriate tooling needed.

What are ceramic knives made of?
These 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 8.2 mohs (vs. steel at 5-6 mohs and diamond at 10 mohs).

Will a ceramic knife break or shatter if I drop it?
Any knife is at risk of damage if thrown in to a sink, dropped or misused. Like a forged steel knife, you can break the tip if the knife lands on it. Fortunately, most damaged tips can be repaired through Kyocera's resharpening service. When properly cared for, it should provide years of service.

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?
No, high-quality knives should always be cleaned by hand, not in dishwashers.

Do Kyocera knives come with a warranty?
All Kyocera knives comes with a five year limited warranty. The warranty only covers manufacturer's faults. The warranty is deemed void if the knifes have been used for cutting bones or crushing garlic. No self-sharpening knives must be sent back to Oceania Trade Link for sharpening.

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 east coast of Japan on the island of Kyushu.

How should I use my Kyocera ceramic knife?
Your Kyocera ceramic knife works 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 a black-HIP blade and a white blade?
A black (HIP) blade is made out of a black zirconium oxide and offers extra durability. This type of blade goes through an extra firing process called a "hot-isostatic press," creating a tighter weave between the ceramic molecules, thus creating a tougher blade. The white ceramic blade is also made out of zirconium oxide but does not go through this expensive sintering process
