These knives feature aogami super steel on the core and the knife is then clad with stainless stainless steel to protect most of the knife from reacting with acids or moisture. These knives will only oxidize right along the edge. Knife sharpeners love aogami super steel because it takes an acute edge and holds it. The knives have high hardness of HRC 62-63.
This Kanehiro Nakiri was straight-razor sharp upon delivery. The metal on this blade is incomprehensibly strong considering the light overall weight of the piece. Truly an exquisite product from a talented smith. Very pleased.
