Aoi Art’s Comment:Ko-Kongo Byoe refers to swordsmiths like Moritsuna, Morisada, and Yoshimori.
This piece, attributed to Ko-Kongo Byoe, is from the Kamakura period.
It features a high shinogi-ji, a suguha-style hamon, and a boshi that rounds and returns gracefully.
The blade exhibits a faint whitish utsuri pattern.
The deep curvature, mixed itame and mokume hada with occasional masame grain, and overall workmanship are hallmarks of this era.
