This is an unsigned Tanto attributed to Nobukuni, a lineage of swordsmiths from Yamashiro province active from the late Nanbokucho period into the early Muromachi period. It features a wide, thick Mitsumune blade with Itame and Mokume jigane and a Nie-deki Suguha hamon. The tanto comes with both a shirasaya and koshirae, and is accompanied by an NBTHK Tokubetsu Hozon Token certificate.

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.
