Package content: 1Dimensions: 15 x 2.5 x 7.6 cmMaterial: CeramicKyocera blades are made primarily of zirconium oxide, which is also found in its raw state in nature. It is a high-performance technical ceramic, which is not comparable to porcelain or household ceramics.High-performance ceramics are primarily used in aerospace and medical engineering, as well as in the electronics and automotive industries. High-purity powder, patented technologies and decades of experience from our ceramic engineers: Kyocera (Advanced Ceramics) high-performance ceramic is an exceptional high-tech material.This material gives a very light blade. It is extremely hard, and resists heat, corrosion and acids. Ceramic blades retain their sharpness for a very long time. Here are all the benefits you can enjoy in the daily use of a Kyocera ceramic knife or kitchen accessory.Mandolins, graters and peelers can be machine washed .Highlights: The ceramic blades do not rust, and do not impart any taste or odor to the food. Ceramic is a neutral material and does not transmit any metallic particles that can contaminate food. No material stays sharp longer than ceramic and the fineness of ceramic allows for a surgical edge.
