The Shun Premier 5 1/2-in. Santoku is part of the beautiful Shun Premier line, which calls to mind the hand-forged knives of ancient Japan. While each knife still takes at least 100 handcrafted steps to complete, the materials Shun uses are among the most advanced in the industry. Each blade has a cutting core of Shun's proprietary VG-MAX “super steel” to take and hold a precision edge. The layered Damascus cladding supports the core and provides additional stain resistance. Near the edge of the blade, where the steels meet, an undulating line is formed—similar to the hamon formed when samurai swords are tempered using a traditional clay-baking technique.
