Shun Premier knives combine a number of advanced elements to truly stand apart from the crowd. The core of the Premier blade is VG-Max steel which is supported by 34 layers of stainless steel on each side of the blade. The layering of steel on the blade creates a Damascus finish which is hammered for a breathtaking finish! The VG-Max steel, hardened to 61 degrees Rockwell, creates the cutting edge of the blade. It is designed to handle being sharpened to a very narrow angle. It will also hold its razor sharp edge for a long time, needing infrequent sharpening. The hand hammered finish reduces friction and keeps foods from sticking to the blade. The beautiful PakkaWood handle is as comfortable as it is beautiful. The aesthetic of the Premier line catches your eye and the extraordinary performance seals the deal. Hand Wash these pieces with mild dish soap, rinse thoroughly, and dry completely. Handcrafted in Japan.
