The Hada is large-grained, the Nioikuchi is deep, there are Sunagashi and Kinsuji apparent well, these characteristics are often seen on Tametsugu swords.
The Hada and the Hamon are really awesome, It makes sense that this sword had been considered made by Norishige.
Unfortunately, there’s a Kizu above Hamachi and Mune, but the sword is still of good quality.
