FUYUHIRO 冬廣, said a son of 3rd generation Sōshu-HIROTSUGU 相州廣次 who had lived in Sōshu province (current Kamakura city) went to live in Obama, Wakasa (current Fukui pref.) to establish FUYUHIRO lineage in Kansho era (1460-). FUYUHIRO lineage enjoyed the confidence from generals and worked in Hōki or Bizen, Bingo or Izumo as well to meet with increasing demand.
During the Warning State period, FUYUHIRO 冬廣 who belonged to Sōshu school had come into constant relationship with raised lineages of Bizen or Mino school like this example and met with increasing demand.
FUYUHIRO family tree had been prospered to NAGANOBU 長信 of the 17th generation FUYUHIORO until end of Edo period.
This katana forms typical Kencho-shinto style that reminds us the scenery of Soshu provenance from Nanbokucho period and being ardently admired by pedigree SHIZU work. Itame-hada forging technique with a rather on stronger side quenching Hamon, both shows resemblance of Sōshu-technique holding full of stirring Samurai spirits.
From it's unique and sublime stroke manner of inscription signature (the last character of "saku" is intentionally small), this katana was made by Tou' Saemon-no-jo FUYUHIRO 藤佐衛門尉冬廣 who was active from Eiroku era (1558-).
