Oblong round shape (nagamaru-gata) tsuba with design of dragonfly (tombo or katsumushi) and wheel (kuruma) in negative openwork (kage-sukashi), round rim (maru-mimi ). Copper sekigane.

Okamoto Yasukazu’s Owari to Mikawa no tankō, №181 characterizes the tsuba as follows: “Katsumushi, kuruma-sukashi no zu (dragonfly and wheel sukashi). Mei: Yamakichibei (Shodai). Such small tsuba are rare for the Shodai. The nakago-ana is also small so it was probably intended to be mounted on a tantō. Regardless of its size, the iron is outstanding and the workmanship shows the characteristic features of the Shodai (first generation). The kuruma-sukashi design is interpreted here in a half-moon shape and only on one side of the tsuba. Such a design is also seen on works of the Nidai (second generation)…”. Signed to the left of nakaga-ana: Yamakichibei (山吉兵へ). Attributed to the First Generation (Shodai) master.
