INNOVATIONwhite™ is a patented technology where design meets function. Kyocera collaborates with Tokyo designer Yohei Kuwano to enhance the knife handle design, inspired by Japanese hammers. Kyocera engineers have developed a nano-refined ceramic [zirconia and alumina] with 2x superior performance and wear resistance. Experience exceptional wear resistance. Discover fast and easy meal preparation. At half the weight of steel knives, these are easier to use, especially for people with arthritis or hand injuries. No sacrificing taste or flavor. Kyocera ceramic knives are non-reactive and non-corrosive. They will never transfer a metallic taste nor contribute to food oxidation.
