About the Shape - Gyuto

The Gyuto (牛刀) is a type of Japanese kitchen knife that has a double-bevel blade, meaning it is sharpened on both sides. It is similar to the western-style chef’s knife, but it is usually thinner, lighter, and sharper. The name Gyuto means “cow sword” in Japanese, because it was originally used for slicing beef.

About the Steel - AUS 8A

Developed by AICHI Techno Metal in Japan, AUS 8A steel, also known as 8A, is a type of stainless steel. It’s part of the AUS series, which includes AUS 4, AUS 6, AUS 8, and AUS 10. The hardness of AUS-8A steel depends on the heat treatment process. It has a Rockwell hardness of 58-59 HRC and can reach up to 60HRC with proper heat treatment. The edge retention of the steel is influenced by its hardness. The harder the steel, the better it retains its edge. At about 59 HRC, the edge retention of AUS-8A stainless steel is considered above average.
