There are several smiths of that name, others smiths men signed as a tribute to your predecessor.

High grade Koshirae:

Tsuka: Honoki wood

Same: Ray skin

Ito: Japanese genuine silk

Menukis: Old traditional work, shakudo with gold

Tsuba: "Chrysanthemum" antique (perhaps Edo) open work fine brass and gold inlay

Tsukamaki katahinerimaki,
Saya with rattan covered, two sections lacquered Ishô-nuri and kuroro. Gold and cooper dust.
Kojiri tsunami (sea waves) with buffalo horn.

Sageo: Silk Murodai (traditional japanese hand work)

The Koshirae is completely rebuilt and restored, it is extremely tight in all its parts to be used for cutting practices and of course mainly for show on a Collection. The Tsuba is surely older (see description above), maybe from the Edo period, only the Tsuba, the rest is more modern but all its parts and elements are Japanese, of course... the restoration of a Koshirae until it is impeccable and very tight is a complicated job that only can do a Japanese grade Master in Koshiraes (Koshiraeshi). Equally, a good polishing (like the one with this blade), only can done a Master polisher (Tobishi). Both recent works are a added value to this item.
