The Metropolitan katana
In the Metropolitan Museum in New York there is a katana remade from a naginata, with a nagasa of 68.4 cm and a sori of 1.9 cm, bequeathed by George C. Stone in 1935. For Sesko it is not by Kaneuji, as had been held, but a shinshintō work, “most likely” by Kurihara Nobuhide or by another smith of the Kiyomaro school.
In the lists and the treatises
He does not appear in Tomita Kiyama’s list of shintō smiths (1933; published in 1935), according to the translation in the Japanese Sword Index. His master, Kiyomaro, does appear in it. No work of his is recorded as a National Treasure, Important Cultural Property or Important Art Object in the sources consulted.
