This is a tsuba with a strong black color, feeling heavy, almost like shakudo. The spaces in the pattern are filled with a slightly large, old-fashioned ishime-ji. It features square kozuka-hitsu and yamagata kogai-hitsu, often seen on older tsuba. Shallowly sukidashi hollyhock and paper mulberry leaves float against the rustic ishime-ji background, with scattered gold and silver dew inlays shining subtly. The tsuba is accompanied by an NBTHK Hozon Tosogu certificate.
