Small saber says Wakizashi with shinogi zukuri blade. Iron Tsuba patterned stylized foliage. Miss the tsuka (handle). Japan period XVIth-XVIIth centuries.
This sword is in its own juice. It is not complete, it misses the tsuka.
A report: scabbard very damaged, damaged and split along the length (trace of glue), missing the kogatana (small knife), pitted blade and oxidized, look at the pictures.
