From Aoi Art: There are some rough texture parts on the blade.
Sayagaki said that Ecchu Koku Norishige. It possesses the atmosphere of Norishige. In any case, there is no doubt that it is Shoshu Den of the period of the Nanbokucho. In the Nakago, there is a gold powder signature. But unfortunately, it is unknown. We recommend this sword.
