Fusamune is well-known among the many swordsmiths who worked in Sagami Province (Sōshū) during the fifteenth and sixteenth centuries. Typical of the style of the late Sōshū school, this blade has tempering effects (hitatsura) visible throughout the surface of the blade, as well as engraving. The luxurious late eighteenth-century mounting is of top quality.
Inscription: Inscribed on the knife blade (kogatana): 豆州住直繼 (Zushū jū Naotsugu) (Naotsugu, residing in Izu Province [present-day Shizuoka Prefecture]); on the sword guard (tsuba): Sōheishi Sōtensai.
