First generation Munemitsu was condidered as a pupil or younger brother of Osafune Nagamitsu. Up to second half of Muromachi period, family name was succeeded generation by generation. This sword was created by Sa-kyô-shin Mune-mitsu who worked during Bun-mei through Kyô-roku. There was a sword with signature "備前國住長船祐光次男左京進宗光作　文明九年二月日"(Bi-zen-(no)-kuni-jyû Osa-fune Suke-mitsu ji-nan(second son) sa-kyô-shin Mune-mitsu tsukuru(create)), so that one could consider he was a son of Roku-rô-za-e-mon Suke-mitsu. His elder brother was U-kyô-no-suke Katsu-mitsu. Also co-created swords exist. It was said that he taught creating the swords for AKA-MATSU Masa-nori. He also created the swords at Bi-chû, Hari-ma, Kyô(Miyako) or Ô-mi.

[ Highlight ]

A little uchi-zori attached. Compared with total length, nakago is relatively long. Small in size though, it shows toughness. Jigane has its cleaness. In its sugu-ha hamon, there are some changes and movement of nie. Kinsens appeared as well. Such kind of textures are shown so much. The more one looks at this tantô the more one can feel the taste of mokumes and utsuri deeply.

[ Conditions ] There is 2 mm long kiri-komi-kizu at edge of hira-ji-mune, middle of omote side. Koshirae metal fitting of kashira gets a little loose. Rest, it maintains fine conditions.
