Shigeki Tanaka Nakiri forged in Ginsan (Gin3 or Silver #3) stainless carbon steel, with 14% added Chromium. Ginsan is similar in hardness to Shirogami #2, but unlike Shirogami steel Ginsan is stainless. It's edge retention is only slightly inferior to Shirogami #2, but the fact that it combines carbon steel characteristics like high edge retention, easy sharpen-ability and ultra sharpness with stainless steel corrosion resistance makes Ginsan a great choice for those who wish to have a Japanese carbon steel knife that is easy to maintain.
So, we have a premium quality stainless steel, forged by a Master Japanese Blacksmith. The blades are stunning with the Nashiji (pear skin) finish and the octagonal walnut and black buffalo handles.
