From Aoi Art: NBTHK judged this sword is Sue-Tegai, but in our opinion, this sword is older so it is Tegai but not Sue-Tegai. Anyway, Ko-Itame-Hada well grained with Jinie and Chikei　, and also Utsuri appear wonderful Jigane. Hamon is clear, Suguha with soft Habuchi and Ko-Ashi worked. Boshi is Yakitsume style. Koshirae is also nice quality and there are no flaws, this peace won’t let you get bored.
