Special feature : First generation Bizen no suke Munetsugu (Koyama Munetugu )
was born at Mutsu Shirakawa province as a son of Koyama Munehira.
His name was Soubei.
He was working for Matudaira Daimyo family as a sword making Samurai.
He moved to Kuwana province with his master and then he moved to
Edo Tenpo 2 nd year.At that time he had high reputation of cut well
swords maker. some times we found his swords which was done
Saidanmei and also possession name on the tang of the blade.
Generally speaking the quality of Munetsugu is one of the top sword
smith in late Edo period and without any faults among his swords.
His reputation was very high because his skill is quite high
I have never seen worst one.
His subjects are overwhelmingly Gunome midare hamon and midarekomi boshi.
The sword are very similar with Cyounsai Tsunatoshi.
The differences of these swords are Tsunatoshi’ s gunome midare devided 2 and round boshi but Munetsugu make midarekomi boshi style.
If the round shaped boshi, you should doubt the signature.
Munetsugu of brother Koyama Munehira, Munetoshi are almost same hamon and jigane.
He had to stop business making swords, by Haitorei.(decree banning the wearing of swords)
This sword is very healthy without Kizu and flow.
The blade has 2 cutting test were done by Yamada Gonzaburo and also ordered name by Yagi Masakame Yamagami cran Kosyu.
I think the blade might upgrade to Jyuyo Token.
We recommend this sword for you.
