Kitchen knife - Steel, Wood - Japan - 伝統的和出刃包丁大小 利研/濃州孫六作 古流

Vintage Japanese Deba Knife Set (2 Pieces) – Signed “Riken” & “Nōshū Magoroku Saku Koryū”
ヴィンテージ和出刃包丁 2本セット – 「利研」「濃州孫六作 古流」銘入り
Offered here is a distinctive pair of vintage Japanese Deba knives, traditional single-bevel knives developed for fish preparation and valued for their robust construction and precise cutting performance.

The larger knife bears the signature 「利研」 (Riken), while the smaller knife is signed 「濃州孫六作 古流」 (Nōshū Magoroku Saku Koryū). Together, these two signed examples reflect the long tradition of Japanese cutlery craftsmanship and provide an interesting combination of practical utility and collectible appeal.

The smaller knife features an attractive hammered-tsuchime finish, creating a visual contrast with the more traditional appearance of the larger example.
