Twelve smiths in Seki forge three hundred kitchen knives a year — by hand, one billet at a time.

Twelve smiths.Three hundredknives a year.

Seki has made blades for seven hundred years. We are a small part of that: one forge, one stone room, and the slow habit of making each knife a little better than the last. That habit has a name — kaizen.

Founded1957

By Mori Tetsuo, in a shed behind his house in Kajiya-machi.

Fourth generation,first light.

Mori Kenji took the hammer from his grandfather in 1994. He still forges every yanagiba himself.

Around him, eleven smiths — the youngest twenty-four, the oldest seventy-one — each with a mark struck into the tang of every knife they touch.
