This katana is attributed to the Ko-Mihara school from Bingo Province, active during the Nanboku-cho period. The Ko-Mihara school is renowned for its Yamato-style craftsmanship, characterized by a straight and elegant suguha Hamon and a distinct 'Mihara Boshi' at the blade's tip. These swords were favored by the samurai for their reliability, sharpness, and craftsmanship.
