Sanada Yukimura(1567-June 3, 1615) was a Japanese samurai, second son of the Sengoku period daimyo Sanada Masayuki(1544-1611). His proper name was Sanada Nobushige, named after Takeda Shingen's younger brother Takeda Nobushige, who was a brave and respected warrior. He and his father were known as being excellent military tacticians. Though their army was very small, they won many battles in which they were outnumbered. Through these feats he would gain fame and forever a place in Japanese history. Sanada Yukimura was called "A Hero who may appear once in hundred years" and "crimson demon of war", and Shimazu Tadatsune(arguably the best performer in the invasion of Korea) called him the "number one warrior in Japan"

This Sanada Yukimura Koshirae reproduces Yoto Muramasa, a cursed blade made by Muramasa, which terrified Tokugawa Ieyasu. It is said that Ieyasu had lost his son, many friends and relatives to Muramasa blades and had cut himself badly with one, so he forbade his samurai to wear Muramasa blade. On other hand, Yukimura was purposely carrying Muramasa and had it on his hand at the battle of Sekigahara.

The fitting ornaments feature luck-bringing gourds with cherry blossom on blackened Fuchi/Kashira, catfishes and gourds on Menuki, and bamboo leaves on 7 cm diameter Tsuba. A synthetic leather purple Tsuka cord is wrapped over the blackened Tsukasame and Saya is lacquered Kuroro(black gloss finish). Top quality silk Sageo features the purple Kikko(tortoiseshell) pattern.

A sand-cased, extra-reinforced zinc/aluminum alloy blade provides the superb balance for the dynamic air-slashing move. Each parts are uncompromisingly hand-assembled by the Japanese sword craftsman, who is expert in making the genuine Japanese sword, Shinken.

The blade is available up to 2.45 shaku.  Weight without Saya is approximately 800 gram(for 2.45 shaku). Proudly made in Japan.
