Ceramic Knife

详情

The ceramic knife is a knife made out of very hard ceramic, often zirconium dioxide. These knives stay sharp longer than steel knives. They are also extremely brittle and will shatter or crack when used to pry. They chip on the edge if used roughly. Usually, though, the edge will merely chip when dropped. Although porcelain is a type of ceramic material, unlike porcelain, ceramic knives do not shatter easily. Zirconia is very hard; it ranks 8.5 on the Mohs scale of mineral hardness, compared to 6 to 6.5 for hardened steel, and *0 for diamond. As such, they cannot be resharpened the same way as steel blades, though they normally come with a special complimentary resharpening service.And the packing is high quality gift packing, so it is a good thing to present to your friends or your relative as a gift.
