Vintage Yoshimasa 10-Piece Oire Nomi Set | Echigo Sanjo, Japan

This is a vintage 10-piece Japanese Oire Nomi (bench chisel) set by Motomiya Yoshimasa (本宮義政) of Motomiya Chisel Works (本宮鑿製作所) in Echigo Sanjo, Niigata, Japan.

The chisels bear the registered maker's mark 「義政」 (Yoshimasa) and were crafted during the late Showa era, circa 1975–1985.
