From Aoi Art: Kunimitsu of the Nanbokucyo Era is the founder of the Uda school, with an unmarked sword from the Taisurijo era. Kunimune and Kunitsugu’s swordsmiths are active, but they are called the Nanbokucyo era, Kouta, since the Kamakura period. Originally due to the flow of Yamato, the Yamato temperament is strong and a strong change appears in the blade crest. This word is beautiful oosuriage mume and deep nioikuchi Kouda and also nice Koshirae, we recommend this sword.
