The Shun Elite Series offers stunningly beautiful design and unparalleled performance. The secret is an advanced steel used to create these attractive blades. The blade begins with a cutting core of SG-2, an exotic Japanese powered steel. Next, each Shun Elite knife is clad with two layers of SUS410 steel, a softer stainless steel that provides additional strength, flexibility, and corrosion resistance. All of this technology means Shun Elite blades will stay sharp several times longer than comparable cutlery, while providing the flexibility and cutting performance top chefs demand.
