T428.  Iron sukashi tsuba.  6.4 x 6.7 x .75 cm.  The nakago hitsu-ana is 1 x 2.6 cm.  A very fun design, if you ask me: an anchor or maybe a grappling hook.  This comes in a slightly unusual box, with a groove to display the tsuba rather than a center post.  There are 2 Kanji on the box top, which I haven’t translated (if any of you can read them please let me know what they say).  Condition is excelent.  $275.
