Artisan Osafune Harumitsu (春光)
Era Tenbun 2 (1533), Muromachi period
Explanation Harumitsu was one of the swordsmiths of Sue-Bizen, and there were several smiths using the same name. Among them, the maker best known is the one who bore the common name Jurōzaemon; besides him there were many Harumitsu who appended various zokumyō (common names), such as Saemon-no-jō, Gorōzaemon-no-jō, Magojurō, Jirōzaemon-no-jō, Gozaemon-no-jō, and Saemon-shichirō. Considered chronologically, works signed Harumitsu span a long period from Bunmei through Bunroku.
This katana bears a production date of Tenbun 2. Although it is of long length, its overall form—with its sakizori—clearly expresses the period style. The jihada shows well-worked and tightly-forged itame, with thickly adhering ji-nie. The hamon is a Sue-Bizen-typical koshi-biraki gunome-midare, and the workmanship as a whole is notably good. It should be regarded as a kessaku (masterpiece) within Harumitsu’s oeuvre.
Harumitsu: signatures include “Bishū no jū Osafune Jurōzaemon-no-jō Fujiwara Harumitsu saku” and “Bishū Zen no Kuni jū Osafune Harumitsu saku.”
(Sue-kotō; ranked chūjō-saku.) It is said that from Kyōroku through the beginning of Tenbun he signed with the name Shinjirō, and thereafter signed as Jurōzaemon-no-jō; he is said to have been the son of Jirōbei-no-jō Harumitsu (治光) and to have been long-lived. His surviving works include swords and tantō; some tantō are of a somewhat stubby proportion with long tangs, and there are also examples in double-edged construction. His hamon may include a suguha tendency in Sue-Bizen style.
