Isshin Hamono Uzanami Kiritsuke Gyuto 170mm AUS-10

Product Description

This Gyuto knife, Kiritsuke Gyuto type, comes from the limited Uzanami (渦波) series by the Japanese manufacturer Isshin Hamono. The series is characterized by a distinctive 67-layer Damascus pattern and a high level of manual craftsmanship, where emphasis is placed not only on performance but also on aesthetics.

The blade is constructed with a san-mai core – a hard core of AUS10 stainless steel (approx. HRC 60) is clad with 67 layers of stainless Damascus steel. This combination provides a very sharp and stable edge, long edge retention, and high corrosion resistance. The knife is suitable for both professional kitchens and demanding home users.

The special hamaguri grind (clamshell profile) ensures a smooth passage of the blade through ingredients, reduces cutting resistance, and limits the adhesion of slices to the blade. The result is a smooth, controlled cut and high comfort even during longer work.

The handle is made of oak wood and treated with traditional Japanese urushi lacquer, which increases resistance to moisture and wear. The octagonal shape provides a secure and balanced grip for both right-handed and left-handed users.

Each piece is hand-finished, and due to its limited production, it is a knife with significant collector's and utility value.

Regular gentle sharpening will extend the life of the edge and maintain optimal cutting ability.
