T393.  Iron tsuba.  7.2 x 7.8 x .7 cm on the rim (.45 cm on the plate).  The nakago hitsu-ana is .9 x 2.7 cm.  A bit unusual, a bit intriguing: the tsuba is quite heavy for its size.  The hitsu-ana are plugged with shakudo and there are remnants of gold zogan on the rim.  Subtle tekkotsu on the rim also.  Condition is excellent.  $225.
