Our Yoshihiro HAP40 High Speed Stainless Steel Nakiri is a state of the art Handcrafted Japanese Chefs knife. HAP40 (Funmatsu Haisu) Stainless Steel holds the potential to become one of the best steels on the stainless steel knife market, maximizing cutting performance and edge retention like not many before.

High Speed Steel is currently considered to be the most advanced stainless steel on the market for high end kitchen knives. A particular significance is the high amount of Cobalt (8%) in the steel alloy which give it its high wear resistance and durability. It makes it perfect for use in its original purpose of industrial machinery, but also excellent in high end kitchen knives which require long lasting edge retention.

It is not easy to forge kitchen knives with High Speed Steel and there are not many knife manufacturers that make the attempt. However, the end results are overwhelmingly positive if done successfully. A particular importance is during heat treatment when the steel reaches in excess of 1200 degrees Celsius. This temperature is extremely high even within forging handcrafted Japanese knives and combined with the state of the art steel, it is what makes the Yoshihiro High Speed Steel Nakiri its exceptional features.
