Features: The Ayakoji school originated from Sadatoshi and included smiths such as Sadayoshi, who were active during the mid-Kamakura period, around the Hoji era (1247\u20131249).
\nThey resided in Shijo Ayano-Koji, Kyoto, and the smith was known by the Buddhist name Ryoa Beya.
\nAccording to sword reference books, Sadatoshi is generally dated to the Bun’ei era, and one theory suggests that he lived near Rai Kuniyuki, with accounts indicating they may have produced swords on each other’s behalf.<\/p>\n

Aoi Art\u2019s Comment: This blade has an antique elegance reminiscent of Awataguchi Kuniyasu.
\nThe Hamon is made up of tightly packed irregular patterns, including small variations with hints of double lines, and a soft appearance along the nioiguchi.
\nAlthough general theory places it in the mid-Kamakura period, around the Bun’ei era (1264\u20131275), the characteristics suggest it may date back earlier, closer to the time of Awataguchi Kuniyasu.
\nThis piece displays Kinsuji in the Hamon, including around the kissaki, giving it a lively and brilliant appearance.
\nIt is a healthy blade with excellent craftsmanship.
\nThe Koshirae is also finely detailed and beautifully made.<\/p>\n
