Not sure about the age of this (Meiji?), but it seems to be an utsushi of a nodachi tsuba from the Futarasan shrine. Suitable as decoration, or for mounting, if you find a sword of the suitable size
I attach pictures of the original at Futarasan.
Measurements:
10.6 x 10.2 x 0.65 cm at mimi., 0.35 at seppa dai
SOLD thank you!
