Yamawaki Hamono Seisakusho
A long-established cutlery maker founded in 1927, producing Sakai kitchen knives under the "Gohumanosuke Yoshihiro" brand in the city of cutlery, Sakai.
Yamawaki Hamono Seisakusho is a maker that inherits the techniques of 600-year-old Sakai cutlery, manufacturing and selling a wide range — from professional-grade high-end kitchen knives for chefs to household knives, and knives for cooking schools and culinary academies. The main brand "Gohumanosuke Yoshihiro" is supported by professionals at home and abroad. The company also supports OEM production and creates one-of-a-kind pieces in collaboration with artisans of other traditional crafts.
Why We Love It
A leader in professional-grade kitchen knives that inherits the tradition of "Sakai cutlery" with its 600-year history. The sharpness of the "Gohumanosuke Yoshihiro" brand, admired by professional chefs, beautifully transforms the cross-section of ingredients and even elevates the flavor. A household santoku knife is also in the lineup, and the maintenance system including re-sharpening is well established — so you can confidently choose it as a lifelong tool.
PROFILE About the Company / Workshop
Yamawaki Hamono Seisakusho was founded in 1927 (Showa 2) in Shukuyacho, Sakai City. Since then, it has continued to manufacture knives used in professional settings, centered on high-end knives for chefs. Today, it also handles household knives and knives for cooking schools and culinary academies, having grown into a comprehensive cutlery maker that responds to a wide range of uses.
A strength of Yamawaki Hamono Seisakusho is finishing each piece in collaboration with artisans for each process — forging, sharpening, and handle-fitting — within the traditional division of labor in Sakai. Its in-house brand "Gohumanosuke Yoshihiro" offers series committed to materials and finishes such as mirror finish and hammered finish, beloved as knives that align with chefs' sensibilities.
In recent years, with the newly built Shukuyacho Sharpening Factory as a base, the company has strengthened its production system. It also focuses on activities to convey the depth of cutlery and the culture of Sakai knives to the next generation — through factory tours, sharing on YouTube and Instagram, and introducing knife types through "Hocho Taizen" (the complete kitchen knife encyclopedia).

The main brand "Gohumanosuke Yoshihiro" earns high acclaim not only from chefs in Japan but also from chefs overseas.
