From Aoi Art: This sword has Shinogiji, Hadame becomes O-Itame, mixed with Masame; you can feel its Koto-ishness, if you take a closer look at this work. The blade is broad and has slightly deep Sori and longer Kissaki, powerful shape. As for Kitai, Itame mixed with Mokume, and there comes Subashiri, Sunagashi, and Kinsuji. It is a real masterpiece we truly recommend for you.
