Our 9½˝ Yoshikane Chef Knife is a hand forged, triple layered structure. The center layer is rust resistant SKD die steel originally designed for cutting metal. The cladding layers are soft SUS-405 stainless steel. This gives the knife an exceedingly tough, long lasting edge and yet is easy to resharpen. The maker Mr. Tsuneo Yoshida is proud of the hand hammered surface which creates a well-balanced knife of lasting beauty. The traditional chestnut handle is charred to expose the grain and produce a beautiful surface texture. In addition, this texture gives a better grip in wet conditions. The blade length is 9½˝, and overall length is 15˝. Each knife is sent with a fully polished razor sharp edge.
