Features: In the Hozon examination, this work was attributed to the Shitahara school, and it is accompanied by an old Tokubetsu Kicho certificate attributing it to Den Seki Kanetomo. The shinogi is notably high in relation to the kasane, giving the blade a substantial and weighty feel.
\nThe Shitahara school was a group of swordsmiths active around Hachioji in Musashi Province from the late Muromachi period through the Edo period. Their workmanship is characterized by dark-toned jigane with prominent jihada and ji-nie activity, including chikei.
\nThe sayagaki by Dr. Kanzan records this blade as a work traditionally attributed to Kanetomo based on an old attribution.
