T220.  Iron tsuba with raised rim and udenukiana.  7.7 x 8.5 x .5 cm.  The nakago hitsu-ana is .7 x 2.8 cm.  The plate is dense, the rim is nicely raised, and there are subtle tekkotsu on the rim.  I can’t be certain but there may have been a signature that was removed.  Condition is excellent.  Was $210, now $150.
