Rare Vintage Japanese Deba Knife Set – “Seki Seiku” & “Registered Yutoyo” Signed – Traditional Hand-Forged Wa-Bocho – Handmade Steel Blades – Japan

希少 ヴィンテージ 日本伝統 和出刃包丁 二本組 「関青空」「登録 祐豊」銘入 手打ち和包丁 ハガネ鋼 日本製

A beautiful and authentic set of vintage Japanese traditional Deba knives (Wa-Bocho), featuring two signed handcrafted blades from Japan.

This lot includes two classic single-bevel Deba knives traditionally used for fish preparation in Japanese cuisine. Their elegant profiles, forged steel construction, and aged patina reflect the craftsmanship of traditional Japanese blacksmithing culture.

The larger knife is signed “Seki Seiku” (関青空) and retains its original handle labels reading “Handmade Highest Grade Product” and “Quality Guaranteed.”

The smaller knife is signed “Registered Yutoyo” (登録 祐豊) and still has the original “Registered Yutoyo Hagane” label on the handle.

These knives are not modern mass-production items — they are genuine vintage Japanese kitchen tools with character, history, and collector appeal.
