[ Highlight ]
The base of the blade is bright, and the blade pattern has regular gunome patterns of nie work, which are almost aligned on the front and back sides. It is thought to have been made between the end of the Edo period and the Meiji period. The right ascension of the signature "Tsugi" and the use of chisels for the fifth stroke of the chiselled blade closely resemble the same characters in a later work by Koyama Munetsugu, which leads us to believe that it was made by Seiryuusai Masatsugu, a member of Koyama Munetsugu's lineage. He is the father of Sakurai Shoji (Manji Shoji) and created swords mainly around the Ganji period.

[ Conditions ] There is slight minor rusting to the blade edge, but it can be preserved and appreciated in its current state.
