How Kyocera Knives Are Made As seen on the Discovery Channel

Like diamonds and sapphires, the elements of ceramic are formed in nature through thousands of years of crystallization, extreme temperatures and literally tons of pressure. The result is a pure, dense, unrelenting material that is harder than steel, close to diamond in hardness.

Kyocera Advanced Ceramics - Kyocera blades are primarily made of zirconium oxide, a naturally occurring raw material. These products are high-performance technical ceramics which cannot be compared with porcelain or household ceramics. High-performance ceramics are used, for example, in the aerospace industry, the medical technology industry, the electronics industry and the car industry. Highly pure powder, patented technologies and decades of experience of our ceramics engineers make Kyocera high-performance ceramics (Advanced Ceramics) a special high-tech material. This material makes the blade very light. The material is extremely hard, resistant to heat and corrosion, and insensitive to acids. Ceramic blades retain their sharpness for a very long time. You will come to appreciate all these advantages during everyday use of a ceramic knife from Kyocera
Cleanliness	Sharpness
Ceramic blades do not rust and do not absorb either the taste or smell of the cut items. Metal ions cannot be transferred to the food.	Even food such as toast, tomatoes and sandwiches can be easily cut. When it comes to the sharpeness of kitchen knives, ceramics is the material of choice.
Light weight	Easy to clean
A Kyocera ceramic knife is extremely light. This reduces symptoms of fatigue during lengthy cutting operations.	The slicers, graters and peelers are dishwasher safe. The ceramic knives are also easy to clean: just wipe with a wet cloth, dry and put away carefully.
