Aoi Art’s Comment: The O-Sa school often shows well-forged jigane resembling the Soshu tradition, similar to works of Samonji.
This piece was originally made in the style of a naginata and later shortened and reshaped into a wakizashi, giving a strong sense of its old period.
If you wish to have the saya relacquered, we can arrange it separately for 15,000 yen.
