Shun Blue Steel is the newest line of fine kitchen cutlery, developed in partnership with award-winning Chef Chris Cosentino. Crafted from Japanese san mai construction consisting of a "blue" carbon steel core sandwiched between two layers of stainless steel. This combination of steels equates to a 61 Rockwell Hardness providing incredible sharpness & edge retention; all the benefits of carbon steel without the additional maintenance. In addition, Blue Steel knives feature a unique knife blade shape that works well when preparing or cutting proteins. Each blade features a beautiful mirror polished finish complemented with a traditional Japanese PakkaWood handle. Shun Blue Steel knives are perfect for the professional & avid home chef. Made in Japan.
