Hiromoto Knives Hiromoto Knives are produced in Seki City, Japan. The knives that we carry are the Aogami Super line and are forged from Blue II Carbon steel, an ultimate Hagane refined from Yasugi sand-irons. These knives are made of high Carbon steel (1.40 - 1.50) with Chromium (0.30 – 0.50) and Tungsten (2.00 – 2.50) added for edge retention and durability. The hardness of the steel measures Rockwell 60-62. The blades are clad with 405 stainless steel to protect from rusting except the cutting edge. The result is an easy to sharpen knife that is durable and perfectly balanced and can hold a razor sharp edge.
