Explanation
During the Shin-to period, Inoue Shinkai was recognized as one of the top swordsmiths alongside Tsuda Echizen-no-kami Sukehira, receiving the highest accolades for new swords. The second generation Kunisada, Inoue Shinkai was the second son of the first Izumi no Kami Kunisada. Initially, he was named Izumi no Kami Kunisada like his father, and after being granted permission to use the kikumon by the court in the 4th year of Manji, he began to call himself Inoue Izumi no Kami Kunisada. Later, in the 12th year of Kanbun, he changed his name to Inoue Shinkai. Shinkai was a superior craftsman compared to his father, producing waves of nioi and displaying remarkable vitality and clarity, earning him a high reputation alongside other top swordsmiths of the new sword era, such as Tsuda Echizen-no-kami Sukehira and Nagasone Kotetsu, eventually being referred to as Osaka Masamune.
This piece is a wakizashi inscribed by Shinkai in the 13th year of Kanbun, recognized as a top-quality work from the new sword era and celebrated as one of the best.

 新刀期、津田越前守助廣と並び西の横綱と称され、新刀最高位の評価を与えられたのがこの井上真改である。 二代国貞、井上真改は初代和泉守国貞の次男であり、初め父同様和泉守国貞と銘し、万治四年に朝廷より菊紋をきることを許さたこの頃から井上和泉守国貞と名のる。その後寛文十二年八月より井上真改と名を改める。真改は父に勝る上手で、沸出来の波紋を焼き粗沸つきその覇気と匂口の冴えは新刀鍛冶中屈指であり、同国の津田越前守助廣や新刀期東の横綱、長曽祢乕徹と並びその技量を高く評価され、大阪正宗と称される程に至った。    本作は延宝三年の真改銘の脇差である。大阪新刀のしっとりとした精美な地鉄に刃文は中直刃を基調にした互の目の交じった沸出来となり、粗沸付き覇気が匂口明るく冴える。新刀最上作にして西の横綱と称される真改の優品である
