Yamasa Gyuto 180mm ZA-18 Steel

Yamasa Hamono is a kitchen knife brand based in the Tosa region, an area in Japan with over 400 years of blade-making history.

Tosa blades are prized for their sharpness, ease of sharpening, and durability. Tosa Sasukemono knives are crafted using a free-forging method, allowing each artisan to create a unique piece that reflects their personal style and craftsmanship.

Yamasa Hamono carries on the traditional blade-forging techniques of the Tosa region. Mr. Tsutomu Kajiwara, a master blacksmith in his 80s, continues to craft knives at Yamasa with expert skill and dedication.

The origins of Yamasa knives are deeply rooted in the culture of blacksmiths—craftsmen who have been creating tools to support local communities since the time of Mr. Tsutomu Kajiwara’s grandfather.

Yamasa Hamono primarily produces traditional-style kitchen knives that are fully handcrafted and affordably priced. The company is continuously working to improve its products with the aim of introducing Yamasa knives to the global market—while preserving the rich, time-honored knife-making culture of Tosa.
