Q368.  Sukashi tsuba.  7.3 x 7.5 x .6 cm.  The nakago hitsu-ana is .9 x 2.8 cm.  Birds fly above grass in this tsuba with a Tokubetsu Kicho paper from the NBTHK, dated 1972, giving it to 3rd Akasaka Tadatora.  There are subtle tekkotsu on the rim and condition is excellent; my pictures should tell you the rest.  $595.
