During the mid-Kamakura to the Nanboku-chō period, the Rai school flourished. The Awataguchi school is famously represented by the six brothers Kuniyuki, Kuniyasu, Kuniyoshi, Arikuni, Kunitsuna, and Kunisada, who were known for their exceptional skills. They continued to produce renowned craftsmen such as Norikuni, Kuniyoshi, Kunimitsu, and Yoshimitsu, and their style has long been praised as "with a blue iron color and white blade." This sword is slender with waist curvature, presenting an ancient form with a small tip. The forging shows an itame-hada with mixed mokume, a slightly thick ji-nuri, with ji-utsuri vividly standing out, and the hamon features a straight blade style mixed with small ko-mizukuri and small irregularities, showing the characteristics of the Awataguchi school. The well-tempered, high-quality steel, combined with the brightness of the ji, results in a graceful appearance, and the groove carved into the waist shows an antique quality. Furthermore, the original state of this sword from its time is very rare, with the tempering still remaining, making it highly valuable and a sight to behold.
