Our Zirconia Ceramic Knives will not tarnish or absorb food odors. They are easy to care for by rinsing in warm water, and they do not need to be fully dried when stored. The translucent blades are made from ceramic zirconia manufactured by Kyocera, the world leader in fine ceramic materials. The master knife maker carefully shapes and sharpens each blade by hand. The Pakka Wood handle is made by compressing very thin slices of wood, pressure treated with resin, to produce a handle which is impervious to water and will last the life of the blade. Each knife comes razor sharp. Instructions for care are included. Overall length: 7¼˝ blade length: 3˝.
