  • Where are Kyocera products made?
    All of Kyocera’s ceramic knives and kitchen tools are designed in Japan. At the same time, all our proprietary zirconia material used for our blades are manufactured in Japan. Our KYOTOP series are exclusively made in Japan. Some of our kitchen tools and Gen series knives are assembled and sharpened in China.

  • How should I use my Kyocera ceramic knife?
    A Kyocera ceramic knife is best for slicing fruits, vegetables, and boneless meats. Even so, ceramic knives are intended to complement -- not replace -- your other cutlery. Use steel knives for carving, prying, boning, cutting frozen foods, and slicing cheese. Avoid flexing or prying.
  • Will a ceramic knife break if I drop it?
    Any knife, whether stainless steel or ceramic, will potentially break if dropped on a hard surface at a certain angle. We offer an outstanding sharpening and repair service removing any chips and sharpen the knife back to its factory edge at a fee.
  • Can I put my ceramic knife in the dishwasher?
    High-quality kitchen cutlery, including Kyocera knives, should not be placed in a dishwasher because over time, handles can warp. The knives are easy to hand wash after use and you can remove any stubborn discoloration on white blades with a mild solution of baking soda and water. If you prefer using the dishwasher, plastic-handled knives and tools knife should be placed on the top rack only.
  • What's so special about Kyocera knives?
    Kyocera’s comprehensive experience and capabilities in advanced ceramic technology have enabled the company to develop kitchen tools and cutlery that are of high-quality and performance. Not all ceramic knives are created equal. These unretouched photos show a Kyocera advanced ceramic blade and another ceramic brand magnified 562 times. Kyocera's micro-grain ceramic is denser, and its cutting edge is sharper.
  • What exactly are Kyocera ceramic knives made of?
    Kyocera ceramic knives are made of an advanced, high-tech ceramic called zirconium oxide (also called zirconia). 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 sharpen your ceramic knife by using a Certified Knife Sharpening service who uses a diamond wheel or purchase a Kyocera home sharpener with a diamond wheel and do it yourself!
  • Can I use a ceramic sharpening rod on a ceramic knife?
    Please don't! The ceramic sharpeners are used to sharpen all steel-based knives, including titanium because the same hardness principle applies. Ceramic is harder than all metals, so it is the ideal surface to re-sharpen these softer materials. For our ceramic knives, a diamond wheel is necessary.
  • What's the difference between a black hot isostatic pressed (HIP) blade in the KYOTOP series and a white blade?
    A black (HIP) blade is made out of 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 sintering process.
  • What is the difference between the black and white blade in the Gen Series?
    There is no difference between the black and white blades in the Revolution series and are made with the same zirconia Z206 ceramic material. However, the Z212 black blade in the Shin Black series is our latest proprietary technology, an extremely dense zirconia that maintains its sharpness 2x longer than our traditional Z206 blades which are used on our Innovation FZ white series knives.
  • What are Kyocera’s ceramic scissors made of?
    These scissors 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).
  • Will ceramic scissors break if I drop them?
    Ceramic scissors will not shatter when dropped. Like forged steel scissors, however, you can break the tip if the scissors land on the tip (very uncommon). You can also damage ceramic scissors by trying to cut very thick material or by trying to bend the blades. Ceramic blades are strong, but not flexible.
