Masakage Koishi Stainless Clad Aogami Super Kurouchi Tsuchime 240mm Gyuto

The Masakage Koishi 240mm Gyuto is a long Japanese chef knife for large vegetables, proteins, herbs, and higher-volume preparation. Its 246mm measured edge provides reach while the gently curved profile supports chopping, slicing, and controlled rocking.

Made in Echizen, Japan, the blade uses an Aogami Super carbon-steel core with stainless cladding and a Kurouchi Tsuchime finish. The core is hardened for strong edge retention and takes a refined edge, while the stainless cladding reduces maintenance on the blade faces. The exposed carbon-steel edge remains reactive and should be washed and dried promptly.

An octagonal cherry-wood Wa handle with black pakkawood ferrule keeps the knife balanced and comfortable in hand. The blade is hand engraved and weighs 190g.
