This 3″ ceramic paring knife is useful for many tasks and is a great introduction to ceramic knives. It features an ergonomic plastic handle and a white blade. Kyocera ceramic knives are made of an advanced, high-tech ceramic called zirconium oxide. This material, which is second in hardness only to diamond, was originally developed for industrial applications where metal components failed. It is extremely hard, wear resistant, and chemically inert. This results in knives that keep their edge and can go months or years without sharpening, do not react with the food that is being prepared, are easy to clean and easy to use. If you do need to sharpen your Kyocera knives, Kyocera themselves offer a sharpening service. All Kyocera knives come with a 5 year warranty.
