Special feature: It is a very rare masterpiece. Kogarasu Maru style sword which made by Gassan Sadakatsu. Gassan Sadakatsu (Eitaro Tsukiyama) was worked from the Taisho era to the early Showa era. He is one of the master craftsmen representing a Japanese swordsmith. Born in 1869 (Meiji 2). The son of the first Gassan Sadayoshi.
He produced many swords for the imperial family and swords dedicated to the shrine Ise Jingu.

From Aoi Art: Gassan Sadakatsu is a very dexterous swordsmith and produces all
kinds of works. The technique is of his father It is said that his skill exceeded his father’s skill, and from the latter half of the Meiji era, he also produced a substitute work for his
father.
This is very difficult work of Kogarasu Maru as a household heirloom, the stem is still shiny without rust. I think it is preferable to have a raw blade(Ubuha) we recommend you to purchase it as your family treasure.
