\nHamon: Made in nie-deki, featuring deep nioiguchi with a flamboyant o-gunome midare.
\nIt resembles cumulonimbus clouds floating in a blue sky, with thick ashi, sunagashi, and kinsuji activities.
\nA spectacular hamon.
\nBoshi: Rounded with a deep nioiguchi that turns back gracefully.<\/p>\n

Features: Dewa Daijo Yukihiro was the younger brother of the first-generation Masahiro and was known as Kurobei.
\nIn Keian 3 (1650), he studied the use of Dutch steel at the age of 32.
\nHe received the title Dewa Daijo in Shoho 5 (1648), and passed away in Tenwa 3 (1683).
\nHis style closely resembles that of Masahiro, and although this work is a superb example of his craftsmanship, it is deeply regrettable that the nakago has been shortened and the signature lost.<\/p>\n

Koshirae:
\nTsuba: Iron tsuba with high-relief carvings of figures\u2014one on a boat by a lakeshore and another on a dragon-shaped vessel\u2014decorated with gold. A distant mountain scene is engraved in the background.
\nFuchikashira: Shakudo nanako ground with raised floral designs, likely peonies, decorated in gold.
\nSaya (Scabbard): Black lacquer with carved patterns.
\nMenuki: Plant motifs carved and highlighted with gold.<\/p>\n

Aoi Art\u2019s Comment: Although unsigned, this work has been attributed to Dewa Daijo Yukihiro and is of the highest quality.
\nIt is very unfortunate that it was shortened and rendered mumei.
\nHad it retained its signature, it may have been designated as Juyo Token.<\/p>\n

Historical Background:\u3000The Edo period was an era of peace.
\nThe focus of sword-making shifted from cutting performance to visual appreciation.
\nMore flamboyant and decorative styles emerged, such as blades with horimono (carvings) and wild t\u014dranba hamon.<\/p>\n
