The Shun Sora 6 inch ultimate utlity knife has the incredibly sharp edge you expect from Shun, but at a great price. This value-priced Shun Sora knife has a VG-10 (super steel) edge welded to a stainless steel core. The expensive VG-10 steel is only used where it's necessary to give you a sharp, durable edge. That's why Shun Sora has such an affordable price. Each side of the edge is also covered with a layer of stainless steel to protect it from corrosion and other damage. Shun Sora cutlery has a balanced and comfortable handle. Made in Japan, the Ultimate Utility Knife from Shun comes with a 10-year Shun warranty with normal use and proper care.
