Collection: Yamatsuka Hamono

The Yamatsuka Hamono factory is located in the coastal industrial area of Sakai City, Osaka Prefecture. The production of knives is led primarily by family members, including Shogo Yamatsuka (山塚尚剛) and his younger brother, Takushi Yamatsuka (山塚拓志).

The most distinctive feature is their use of a metal called "Gin-san". Gin-san is a high-carbon stainless steel manufactured by Hitachi Metals.

According to the Sakai Cutlery Association, Yamatsuka Hamono has a history spanning over 170 years. The Yamatsuka brothers have been involved in their father's factory since childhood.

Yamatsuka Hamono manufactures many Gin-san knives as OEM products for retailers and wholesalers. Ichie Hamono, however, sell knives under Yamatsuka's original brand "Sakai Yamatsuka".

 The knives from Yamatsuka Hamono we carry are sharpened by either Tosafuku Hamono(土佐福刃物製作所), Mitsuo Yamatsuka (山塚光雄), or Fujii Hamono (藤井刃物製作所).
