Special feature: This sword has 2 judgements, Suebizen and Uda. Tsuruta thinks that Uda is the most reliable judgement. Apparently, it looks like ones from the Nambokucho period, but it has not only blackish rough Jigane with Chikei: which is like Kobizen, but also Boshi of Midarekomi. They are strong characteristics of Uda swords.

From Aoi Art: Generally, blackish Nagaremasa with Chikei means Uda school. Moreover, its Boshi is Midarekomi: it looks just like Kitagunimono. We deal with this work as Uda according to the Judgement of Fujishiro. The polish is also nicely done and it has no critical flaws. We truly recommend this well-made sword with marvelous Hamon.
