Katana signed by Kunimasa, a pupil of Horikawa Kunihiro in Kyoto (Yamashiro province) in the early Edo period. According to the original seller, his signed works are extremely rare and his work matches the master's in style, tang finish and signature calligraphy, which is why he is regarded as one of Kunihiro's daisaku smiths (works made in the master's name); some signatures indicate that he later worked in Edo. The blade, shinogi-zukuri with iori-mune, shallow sori and chū-kissaki, measures 70.8 cm in nagasa with 1.1 cm of sori. The Jūyō description records an itame standing out with ji-nie and a notare hamon mixed with gunome, with ashi, deep nioi, ko-nie, sunagashi and faint kinsuji; the bōshi runs straight and turns back in a round tip. The photographs show the ubu tang, with kurijiri tip, ō-sujikai file marks, a single mekugi-ana and the signature 国正 (Kunimasa) below the hole, towards the back.
