T524.  Pine tree sukashi.  7.9 x 8.1 x .45 cm.  The nakago hitsu-ana is .8 x 3.1 cm.  I found this tsuba covered in clear finish and needing some caring attention; it cleaned up quite nicely I think.  I don’t know which school this come from; you get to decide.  There is a small spot of weak patina on the seppa-dai; otherwise condition is excellent.  $275.
