Aoi Art’s Comment: The polishing of this sword is exceptional, bringing out the beauty and clarity of the steel. The blending of the ground metal (ji) and patterned metal (hamon) suggests it might be a pure forged blade. The surface texture resembles the clear steel of the Aoe school. There is a vertical crack on the kissaki (tip), but it is not a major concern. Overall, it is a highly recommended top-quality Kosanbara.

Historical Background: During the later period of the Kamakura era, transportation flourished nationwide, and ports became vibrant, giving rise to economically powerful samurai. The dissatisfaction towards the Hojo clan, who sought to strengthen their power, gradually intensified. Emperor Go-Daigo aimed to regain political control of the court and eventually overthrew the Kamakura shogunate by gaining support from newly
emerging samurai and retainers.
