This presenting Katana is attributed to Ko-Mihara-School by 44. Juyo Token Meeting. Here we have an especially beautiful, real good conditioned sword with nice, plain mounts and black lacquered Koshirae.
The Mihara- School was founded end of Kamakura- Jidai in the province of Bingo and reached late Muromachi. Blades of Kamakura times are called Ko-Mihara, like this Katana.
This sword has all characteristics of Ko-Mihara-School, as you can see easily on the pictures. It`s in a perfect condition, with very nice polish.
