T240.  Iron tsuba signed Kaneiye Saku.  8.1 x 8.4 x .5 cm.  The nakago hitsu-ana is .8 x 2.6 cm.  There is one very small sukashi, punch work and carving, subtle tekkotsu on the rim, silver & brass ten zogan and very fine copper inlay.  Not sure what the design is (anyone out there know?) but it puts me in mind of Buddhist symbolism.  A tiny bit of the fine copper is missing.

This tsuba comes with a paper, issued in Japan in 2014, by the NTHK-NPO.  The paper says “Kaneiye Saku” and “Edo Shoki” (early Edo).  Comes also with a box with pillow.  The label on the box says “Kaneiye Saku” and “3 Kanji Mei”.

Condition is excellent.  $300.  (Heck, the paper probably cost nearly that much.)
