T397.  Otafuku mokko (shape) iron tsuba with udenuki-ana.  6.5 x 8 x .4 cm on the raised rim (.3 cm on the plate).  The nakago hitsu-ana is .8 x 2.7 cm.  Great material here: ample tekkotsu and a wonderful patina.  There may have been a signature at one time, not sure, but if there was it has been lost.  Condition is excellent.  $195.
