This katana is attributed to the Senjuin school, active from the late Kamakura to Nanbokucho period in Yamato province. It features a flowing itame-hada with masame, ji-nie, and chikei, showing a lively and varied jigane. The hamon is suguha mixed with ko-gunome, with abundant nie, kinsuji, and sunagashi, forming a double-edged effect with tobiyaki. The blade is in good condition, with a slight forge flaw in the bo-hi.
