The blade comes with a NBTHK Tokubetsu Kicho Certificate for both the blade and its koshirae. The koshirae features autumn-themed motifs on the Fuchi-Kashira, a peony-themed Menuki, and a dragon-themed Saya, showcasing fine craftsmanship.

Few Kyoto houses bridged two traditions as deliberately as Nobukuni (信国), the Yamashiro-den lineage whose work runs from the Nanbokucho period through Muromachi and on, in a western branch, into the shinto age. The first generation, the smith the NBTHK counts as shodai, is the master of the Enbun, Koan and Joji years; the older registers placed a founding Nobukuni back in the Kenmu era, but the published sources set that legend aside, since no work survives so early and the style of the oldest dated blades connects directly with that of Sadamune.
