Rare And Very Powerful Mumei Shinshinto Katana Blade, Late Edo And Its Very Beautiful Koshirae

Rare, long and very powerful Katana Mumei Shinshinto blade (19th century), from the end of the Edo period, “Boshin War” (1868/1869), with a Hamon Hiro-Suguha (wide) and a Masame-hada. The blade is mounted in a very beautiful period Koshirae.

To date, very few such imposing blades have been produced, making it a fairly rare piece.

The Tsuka is braided in Hineri-maki with a Golden Ito in natural Japanese silk and a Same with Oya-tsubo (emperor nodules). All in a very beautiful Japanese brocade cover. The Saya is lacquered with a magnificent pattern imitating red Chinese birch bark and equipped with a Sageo in natural Japanese Golden silk, braided in Ronin-musubi.

This Shinshinto blade was forged in the manner of those forged during the Momoyama Period (1573-1643). It is for this reason that this imposing blade, long (77.7cm at Nagasa) and heavy (1280grs, bare blade) is particularly rare.
