K245.  Very thin plate sukashi tsuba.  8 x 8.4 x .2 cm.  The nakago hitsu-ana is .8 x 3.1 cm.  The sukashi might be a dragonfly (3 wing?) but probably something else.  Whatever; this is an interesting tsuba with fine tekkotsu on the rim.  This came out of the box of 108 that was found in a kura (storehouse) in Japan.  $295.
