Ittosai Kotetsu hammered kurouchi 240mm wa-gyuto is a Japanese chef's knife from Sakai, Japan. Featuring Shirogami #1 core steel prized for its peak sharpness, this knife benefits from Tanaka-san's renowned heat treatment, which optimizes the steel's balance of hardness, toughness, and sharpenability. The blade has reactive iron cladding and a tsuchime kurouchi finish. It delivers exceptional performance for both home cooks and professional chefs.

Notes:
a. For the care and maintenance of Japanese kitchen knives, such as this hammered gyuto knife, please refer to our care guide below.
b. Slight measurement variations are common in Japanese kitchen knives.
c. Small surface finish variations in knives are a normal part of the handcrafting process.
d. The faded spots on this knife are normal. This is an authentic kurouchi finish, not a 'painted' or chemically forced synthetic finish with a super smooth and homogenous appearance seen on other brands. Each Tanaka kurouchi knife in this series will show these natural variations.
