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.

He was well kown swordsmith at that time and left some unique episodes.
When Kiyomaro opened a sword factory near Munetsugu without saying Hello to Munetsugu. So he got anger and tried to duel Kiyomaro.
I don’t know the result but his intense feeling was succeeded to make swords.
He tried to make cut well swords so he asked Yamada Asaemon how to cut well with swords.
So Koyama Munetsugu has so many Saidanmei swords during his life.
