This is a long, classic yanagiba (柳刃包丁)—the kind of blade that would have lived behind a sushi counter where knives were chosen for feel and sharpening response more than for branding. The length and slim profile speak to the old Kansai sashimi tradition, when a cook’s knife was maintained for decades and the story of the tool was written in the steel itself. The subtle patina and scattered spotting suggest real kitchen life—salt, protein, and time—rather than a modern collector’s piece. The understated wa handle keeps it grounded and practical, the kind of handle you’d expect on a working yanagiba meant to be sharpened often and trusted daily.
