Kyocera Technology

Kyocera shows independent testing and comparison against high carbon and stainless steel as well as other ceramic knife manufacturers. Learn about a material that is only second in hardness to diamond.

Unrelenting Sharpness

Kyocera advanced ceramic blades offer superior edge retention, holding their edge at least 10 times longer than other professional blades, including high carbon steel.

Brand new ceramic, high carbon and stainless steel knives were put into a Honda “sharpness testing” machine. The tester holds each blade with a constant force against a stack of paper and then slides the blade 3.5 inches to produce a slicing action. Paper was used because it’s much more abrasive than vegetables. As the test is repeated 1,000 times, the ceramic blade stays sharper longer than the other two blades.



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 more dense, and its cutting edge is sharper - just two reasons that Kyocera is the undisputed worldwide leader in ceramic cutlery.

Unparalleled Purity

Because they’re ceramic, Kyocera knives and kitchen tools won’t brown foods, won’t transfer a metallic taste or smell, and will never rust.

Ultra lightweight

Perfectly balanced and lightweight, Kyocera ceramic knives reduce fatigue during repetitive cutting tasks.



Advanced Ceramics: formed by nature, perfected by science

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 50% harder than steel, close to diamond in hardness.

Advanced ceramic is second only to diamond in hardness

Long-wearing and corrosion-free, ceramic parts are often used in bone replacement procedures

In fact, ceramic components are used in satellites, racecar brake pads and other applications that require extreme wear-resistance. For those components that would virtually disintegrate if made from metal, ceramic is the material of choice.
