【Description】
This blade is signed by Koyama Munetsugu (固山宗次) in in Musashi province (Today’s Tokyo) in the 6th year of Tenpo (1835) in Musashi province (Today’s Tokyo). He is also known as the name of Fujiwara Munetsugu (備前助藤原宗次).
Munetsugu’s birthname name was Koyama Sobei (固山宗兵衛). He was born as the third son of Koyama Munehira(固山宗平) in Shirakawa domain in Mutsu province (today’s Fukushima prefecture) in 1803. It is said that he learned the sword-forging technique from Kato Tsunahide (加藤綱英) first and was also an apprentice of
Chounsai Tsunatoshi (長運斎綱俊)
, a younger brother of Tsunahide to improve his craftsmanship. He worked for the Hisamatsu-Matsudaira family of the Shirakawa domain, and Matsudaira Sadanobu, whom he served, is widely known in Japan as one of the most famous politicians of the Edo period.
His work reflects Bizen Den, one of the five most traditional Japanese sword-forging techniques (五箇伝). He was excellent at forging blades with Choji Gunome Midare tempering line, one of the most noticeable characteristics of Bizen Tradition. He was active in sword-forging during 1830-1870. He is arguably the finest smith working in the Bizen tradition at the end of the Edo period.

Hawk is an intelligent bird used for hunting, called falconry. It was famous as a recreation among high-class Samurais. In the old days, it was also familiar with emperors and royal families, so it might be why the hawk was regarded as a symbol of the ruler’s authority. During the warring period, the boy’s success was to become an excellent Samurai; therefore, it has been thought that men (Samurai) and the hawk had a deep connection as a symbol of advancement and authority. Many Samurais loved this design based on that reason.
Furthermore, its wings were used for one of Samurai’s primary weapons; an arrow (They put hawk’s wings as arrow’s feather).

Still today, various family crests use this bird wing’s motif.
