...the lower left hole looks a bit like a bat... ?
I own also a very poor wakizashi tsuba and I'm intersted in any thougths about it (I don't want to start a new thread with this "miserable" piece):
The dates which I found out but I'm not sure if it's correct:
67 x 62 mm,
Kiku mon
Sukashi bori (right term?) - the spokes are inserted and partly lost pieces
Saotome school ???
Age: ???
Can this be confirmed or do you have other ideas?
