Shun Premier 10" Chef Knife. The newly introduced Shun Premier line combines an authentic Japanese hand hammered look with the quality and performance that Shun is known for. The blade is made of VG10 steel clad with 16 layers on either side of the stainless Damascus, then beveled for lateral stability and precision. Where the steels meet, a wavy line called a "hamon" is formed. The hammered finished is known in Japanese as "tsuchime" and adds a striking appearance to the knife and also acts as hollow ground cavaties that reduce drag and quickly release food from the blade.
