Special feature: Kaneuji who was one of Masamune Juttetsu and his students Kanetomo, kanetsugu, Kaneshige, Kanenobu, and others moved to the Naoe and made swords, so they are collectively called Naoe Shizu. This sword is Oosuruage Mumei, but it is wide and has slightly deep sori, and the center is stretched.
The Jigane is well kneaded, cloves are mixed with each other.
the inside of the Hamon, Ashi tenter well, Kinsuji works vigorously and Sunagashi enters. It represents the highlight of Naoeshizu and is full of
courage, and it is thought that Masamune also had such a blade
crest. Particularly, the Jigane is well kneaded and the scenery is
included, making it a unique strong ground iron.

From Aoi Art: According to the Ryuyo Token book, the
ultimate is affirmed with a bite that expresses the highlights of Naoe
Shizu. The work of the ground blade stands out
It is stated that it is an excellent product of the same group and is in
good condition.
In my opinion, the bullion is particularly characteristic, and the stir-
fried skin is well kneaded, the scenery is included, the blade pattern
can be boiled, and the Sunagashi and gold streaks are prosperous.
I am impressed by the work that works and reminds me of Masamune.
I think NBTHK issued Oshigata is not so good so I recommend to see Aoi Bijyutsu Oshigata
The Jyuyo token book is quite simplified, so our company ‘Oshigata is much better.
Polishing is done by one of the highest polishers in Japan.
We strongly recommend this fantastic sword to you.
