A large Kagamishi tsuba with early style hitsuana.
A very simple design that would work equally well in either orientation. It appears to me to be cast, but a previous owner’s label attributes it to ko-kinko. In some cases it can be difficult to say whether a piece is cast or carved.
Not much to see on the rim, but for the record.
And a detail view with traces of black lacquer remaining.
A similar guard with likely later modification.
And a not so similar guard from Sasano-sensei’s Kagamishi book that combines similar decorative motifs.
