T417.  Iron sukashi tsuba.  8.6 x 8.6 x .45 cm.  The nakago hitsu-ana is .8 x 2.7 cm.  Bell crickets are the theme: insects loved in Japan for their high pitched trilling song.  This is a large tsuba with tiny tekkotsu and tsuchime finish on the rim.  I like this one.

Condition is excellent.  $325.
