Kato Knife Manufacturing — or カトウ打刃物製作所 — has its roots in the postwar era of Echizen blade-making. The workshop traces back to 1948, when the Kato family first established themselves in what would eventually become the Takefu Knife Village cooperative. Hiroshi Kato (加藤 弘), the second-generation master, spent over fifty years at the anvil and was instrumental in co-founding the Takefu Knife Village itself — the cooperative that would bring together some of Echizen's finest blacksmiths under one roof.

Yoshimi Kato's path to the forge is one of the more unusual ones in the industry. Before picking up a hammer, he worked as a project manager in construction. It was only after marrying into the Kato family that he began his apprenticeship under Hiroshi. What makes his story remarkable is the speed — Yoshimi took over the smithy after just five years, a timeline that typically takes fifteen or more. He trained alongside Yu Kurosaki and other masters at Takefu Knife Village, absorbing decades of collective knowledge at an extraordinary pace. In 2008, he earned his certification as a traditional craftsman (伝統工芸士), and in 2018 he formally took over the business.

Today, Kato is best known internationally as the “Master of Damascus.” His multi-layer Damascus patterns are among the most striking in the industry, but what sets him apart is the consistency of his heat treatment across a wide range of steels — from SG2 and VG10 to Aogami Super and Ginsan. Every step of production happens in-house, giving him complete control over the final product. The Kintaro and Kanehiro lines, both produced under the Kato workshop, have built a devoted following among enthusiasts who value the combination of visual artistry and genuine cutting performance.
