Width at the hamachi: 3.1 cm or 1.22 inches.
Kasane: 0.48 cm or 0.19 inches.
The weight of the sword: 320grams
Era: The Nambokucho period.
Shape: Made from Naginata. The blade is broad and thick, solid work.
Jigane: Well-grained Koitame-hada with lots of Jinie. Jigane reminds us of well-grained Tametsugu.
Hamon: Well-grained Itame-hada, Gunome-midare with deep Nioikuchi, from the middle part Nioikuchi goes deeper, and after that Nioikuchi goes much deeper and Boshi ends with Hakigake style.

Special Feature: This is a Nagamaki-ish work and apparently it is like Tametsugu, but NBTHK has judged this as Naoe Shizu and approved it as Tokubetsu Hozon Token. Both swordsmiths made drastic Hamon. This work has especially great brightness from near Monouchi.

From Aoi Art: This work was judged as Naoe Shizu and has a lot of Hataraki, especially in Hachu. It is a really bright blade. Kinsuji works well in Boshi and it is a true well-made work.
