The gunsmith of the New Swords era Hashimoto Sadenjiro Masahiro 1st
Hashimoto Sadenjiro (Masahiro I) was the grandson of Tadahiro I (the founder of the Hizen Tadayoshi School). He was the son of Tadayoshi’s son-in-law Hashimoto Yoshinobu.
The lord of Saga-ha daimyo Nabeshima Katsushige (1580 –1657) especially favored this blacksmith, charging to him the fulfillment of the most important orders.
Masahiro 1st passed away at the age of 59. Masahiro went on to start his own line of smiths, which forged swords up to the end XIX of the century.
This katana is an example of the early art of a gunsmith. The deeply curved blade is forged and hardened in the best tradition of Hizen. The sword, along with the presented koshirae, was one of the highly revered relics of the famous samurai family of Hosokawa and has been passed down from generation to generation for a long time.
