Study:
The Bingo Mihara branch originates in the Yamato tradition. The Mihara school  三原派 stem when some Yamato smiths settled in the Bingo province.
The founder of the Mihara school is Masaiye, 正家 6th generation, during the Tokuji era (1306-1308) at the end of the Kamakura era. One should notice that there are also some trails of a smith name Asaiye, but during the Tenpyō era (729-749). It is said that the Masaiye from the end of Kamakura, and founder of the Mihara, is in fact the renew of this former extinguished branch.

There's 3 periods in the evolution of the Mihara school: until the Oei era (1394) it is the "Ko Mihara"; from Oei era to the Eikyo era (1429) it's known as the "Chū Mihara", and further on it's named the "Sue Mihara".
The productions from the "Ko Mihara" are a very high end quality and historically significant, many being awarded, although being Mumei (not signed) the NBTHK Juyo Token Certificate.

The Kinashi 木梨, Sue mihara 末三原, Hokke 法華, Tatubo 辰房, Goami 五阿弥, Kai 貝, Tomo 鞆 and Goami 其阿弥 schools are all afiiliated to this Mihara branch.
These schools were located in the nowadays Onomichi district, part of the Hiroshima prefecture, where the ancient Bingo province was located.
One of the particularity of the Mihara school is its 'conservative' side, with the often sober anc classical quenching lines.as the Suguha (straight quenching line), which denote frome the other productions of the Bizen province, where most of the other smiths have flamboyant quenching lines like in the Ichimonji school.

This blade here comes from the "Kai" group, located in the Mihara town. This town is known for the ruins of its castle founded in the 16th century, Mihara-Jo, nicknamed "The floating castle" (Ukishiro).
The smith Masanobu (正信) was active during the Tensho era (1573-1592) in the Bingo province for the Kai Mihara group.
The steel of this blade is very similar to the productions of the Bitchu Aoe branch. The hamon is made of Ko-Nie and Nioi Deki. This another typical technical point the Koto/ Muromachi blade, The Shirake Utsui is perceptible in the Ji.
