Shun Elite Cutlery offers stunning beauty and unparalleled quality and performance. The blades of this Shun series feature a core of SG-2, an exotic Japanese powdered steel, and are clad with two layers of SUS410, a softer stainless steel that brings strength, flexibility and corrosion resistance to the knives. This combination of materials helps the blades stay sharper longer than other cutlery in its category.
