\nShape:This tachi features a deep curvature and a slightly wavy kissaki, with an ubu-nakago (original, unaltered tang), allowing for a clear observation of its original form and shinogi-ji details from the time of its creation. The shinogi-ji activity is particularly well preserved.
\nJigane:The ko-itame hada is well-forged, with utsuri appearing, characteristic of old Naminohira swords.
\nHamon:A nioi-based suguha (straight temper line) with some slight clouding near the tip. The boshi is irregular.<\/p>\n

Special Feature:\u3000Naminohira is a group of swordstmiths in Satsuma that originated from Masakuni and his son Yukiyasu, who emigrated from Yamato to Satsuma in the late Heian period and continued until the late Edo period .The style is strongly characteristic of the Yamato style, but often has strong Masa and forms in Ayasugi hada. <\/p>\n

Aoi Art\u2019s Comment:This sword is rare for being in ubu-nakago condition, which allows us to see the original form clearly. It exhibits distinct characteristics of the Ko-Naminohira school, including a well-preserved sori (curvature). The hamon follows the traditional suguha style typical of the period and is considered a reasonably well-made example of its kind.<\/p>\n
