Ancient times in Bungo province (now in Oita pref.) of 12th century, the famed sword smiths monk SADAHIDE 定秀 or YUKIHIRA 行平 had come out, then for a long ages in 14th century of Nanbokucho period, smith TOMOYUKI 友行 appeared in Takada town. TOMOYUKI 友行 is the famed sword maker for the founder of Bungo Takada school in medieval period. According to a classic, TOMOYUKI 友行 had learned Soshu-Bizen school technique in Osafune, Bizen province and also took lessons from SADAMUNE 貞宗 in Kamakura, Soshu province. Those makers in Takada school during Muromachi age used to named prefix Taira 平 whereas on after Shinto period, most of sword makers added a name of clan Fujiwara 藤原 and used a suffix YUKI 行 in their smith name. NORIYUKI 則行 lineage performed 5 major traditions very well and had been succeeded throughout Edo period until the 9th generation to meet with transformed preferences from Samurai class or taste from townspeople. The subject katana was made by 1st generation NORIYUKI 則行 who was active during Kanbun era (1661-), real name Abe Saburo'emon 阿部三郎右衛門 and was apprenticed to Aizawa MASAYUKI 藍沢正行. He followed the example of HIROMASA 広正 or TSUNAHIRO 綱広 from Soshu tradition, using powerfully forged steel chiselled as true folded 真鍛 for the most durable blade construction and Hitatsura 皆焼 temper proves supreme sharp performance. with) Brown stone surface lacquered scabbard Uchikatana Koshirae (click HERE for entire koshirae image and HERE for higher resolution images for each metal fitting)
