About this sword :  This is an Ukai school katana from the late Kamakura period. The Ukai group is a Bizen school that had their roots in Yamashiro. A mixing of the two schools can be seen in thier works as with this example. The deki of this blade is very simmilar to the style of Kagemitsu, Rai Kunitoshi and Yamato Norinaga.

This katana has an 2015 NBTHK Tokubetsu Hozon paper that attributes it to the Ukan School. Ukan is antoher way to say Ukai. The accompanying saya-gaki of this blade is by Honami Koson. It is dated February of 1943. Honami Koson attributed this blade to Unsho. Unsho is considered as a founder of the Ukai school. (Some sources, site Unjo as the founder, who was Unsho's father.) Honami Koson is one of the highest regarded names in the history of sword appraisal. This saya-gaki is a precious one. Unjo is ranked as Jo Saku by Fujishiro and given ten million yen in the Tokotaikan.

This blade is in full Japanese polish. There are kitae-ware present and areas of coarse hada. Ware and rough hada are not uncommon in blades of this age.

This blade is nearly 29 inches in nagasa now and the ubu-ana is near the jiri of the nakago. Its amazing to think of how incredibly long this was when it was newly made. It is difficult to find such a long Tokubetsu Hozon, Kamakura period katana nowadays and even more so in this price range. In addition to the saya with Honami Kosan's sayagaki and the NBTHK Tokubestu Hozon paper, this blade comes with gold foil double habaki and a storage bag. A rare opportunity to acquire a long Tokubestu Hozon Kamakura period blade.
