This 160mm Deba carries the Masamune name from Seki, Japan’s centuries-old blade-making capital. Forged as a working knife, it represents the tradition of Seki smiths who brought sword-making skills into the kitchen, producing sturdy and practical blades for fish butchery. Compact yet weighty, this Deba shows the honest character of tools made for daily use — a piece that connects the owner directly to Japan’s postwar culinary workshops and the enduring reputation of Seki’s Masamune line.
