This is a katana attributed to the Fujishima school, dating to the early Muromachi period. The blade is o-suriage mumei (greatly shortened and unsigned). The Fujishima school, known for the smith Tomoshige, began in the Nanbokucho period and flourished around the Oei era, with its lineage active until the Edo period.

Among the provincial lineages of the Hokurikudo, the Fujishima school took its name and its base from the village of Fujishima in Kaga province, where Tomoshige stands as founder and the name he set down passed through several generations from the close of the Nanbokucho period across the Muromachi and on into the early-modern Shinto era. The members place the chronological anchor with care: the earliest firmly dated work is a tanto of Oei 2 (1395), and the NBTHK finds nothing among the surviving blades that goes back earlier than Nanbokucho.
