The subject tachi created in an archaic style was made by MORIHISA 守久 in Osafune, Bizen province from the 14th C. the period of the Northern and Southern Dynasties. During the 60 years disturbance Nanbokucho period, sword makers raised in power to meet with increasing demand from brave Samurais. Tachi swords became extremely long sublimated such as 3 shaku (90cm) or even more.
The mainstream KANEMITSU 兼光 of the traditional Osafune was still in main force while their branches Kozori 小反り school took a major role of supplement to meet with increasing demand. Whereas individual arisen maker such as Chougi 長義, Motoshige 元重 or Omiya 大宮 school occurred in Bizen province.
According to the NihontoMeikan, MORIHISA 守久 was active during Teiji era (1362-) in the Northern and Southern Dynasties. The original length of this Tachi was as long as about 78.5cm and was being shortened to meet with transition of battle style from Tachi to Kanata in two hundred years during Muromachi period.
This tachi reminds us of it's original shape standing firmly on base, still holds a highly defined curve near the base, generous curved - unrestricted shape with an elongated Chu-Kissaki which is a clear statement of it's age from Nanbokucho. Forging with carefully selected fine steel under traditional Bizen Osafune tradition generates Midare-Utsuri sparkling mottled reflection like a valley where fog hangs low.
