The Shun Elite knives are the ultimate mixture of metal technology and traditional Japanese functional beauty. The core of a Shun Elite knife is SG-2 exotic powdered steel that is hardened under pressure & heat into a hard and dense alloy. The Rockwell hardness rating of Shun Elite is 64, in contrast to most kitchen cutlery ranging from 56 to 58 Rockwell. The SG-2 molecular structure is the finest in use today, allowing the creation of an edge that lasts longer than any other available today. The cutting edge is smooth and very sharp, yet will still work well with a honing rod if needed. The Shun Elite knife core is then clad between two layers of premium 410A stainless steel. The outer layers of the Shun Elite knife blade add flexibility, corrosion resistance, beauty and strength to the knife, as well as some stick-resistance when cutting. The Shun Elite knife handles are a mix of ornate beauty and performance. The durable laminated hardwood PakkaWood ergonomic handles provide a sturdy but comfortable feel to the knife. The handles are detailed with thin rings of brass and copper, plus inlaid with a traditional Japanese symbol. Kershaw Shun Elite knives have a limited lifetime warranty from KAI USA. Hand wash recommended. Made in Seki City, Japan.
