The first Fuyuhiro is said to be the son of the second Hirotsugu who was in Soshu. After studying Soshu-den, he moved to Obama, Wakasa, around 1460 and began making swords. He was a prominent swordsmith who was very trusted by warlords in western Japan because of his excellent quality. After the first generation, his successors continued to make swords under the same name through successive generations until the Edo period (1603-1868), making Fuyuhiro one of the most prestigious swordsmiths in the Wakasa region.

This tanto is a well-preserved piece with the signature of Fuyuhiro. The shape of the unokubi is similar to that of a shobu, and the hada is the traditional Soshu-den itame, a very bright and brilliant workmanship. Hamon is a mixture of gunome and midare with nie on sashi-mote. Sashi-ura has ko-gunome with notare and has a completely different look on the front and back. The blade has a hi engraved on it. On the sashi-omote there is a soe-hi of about 8 cm, but we can assume that this is not original and was added at a later date. The koshirae is shirasaya. The wooden habaki and tsuka are one piece. This is an opportunity to own a koto period fuyuhiro at an unbeatable price.
