About this sword :   The first generation Kunisada was born in the seventeenth year of Tensho (1589). His place of birth was central Kyushu, in Obi-han in the prefecture of Hyuga. He became a student of Horikawa Kunihiro, who was also from Obi, Hyuga. The common theory among sword scholars is that Kunisada was actually a student of Kunitomo, one of Kunihiro's leading students. It is also most probable that Kunitomo was Kunihiro's nephew. Like Kunihiro and Kunisada, Kunitomo was also born in Obi, Hyuga.

After spending several years as an apprentice under Kunitomo, Kunisada became independent and moved to Osaka. Another student of Kunitomo's, Kunisuke, also moved to Osaka about this same time.

Osaka was then a newly developing town. Toyotomi Hideyoshi began construction of his huge castle there in 1584 and it was completed in 1585. Hideyoshi died in 1598 and the lord of the castle became his son, Hideyori. The castle was destroyed by Tokugawa Ieyasu in the so called Osaka Winter and Osaka Summer campaigns of 1614-1615. The city of Osaka was also destroyed. Hideyori and his mother, Yodo, both committed suicide at the end of the war. The Tokugawa Shogunate then established an office in Osaka in 1619. It was called the Osaka Jodai. They started rebuilding the city and the castle at that time.

Kunisada worked steadily from 1623 to around 1645. He signed most of his blades with the mei, "Izumi-no-kami Fujiwara Kunisada". Sometimes he used "Izumi-no-kami Kunisada" or "At Osaka Izumi-no-kami Kunisada".

The mei of this work bears the Izumi no kami title that Shodai Kunisada received in 1623 and it is Shodai Kunisada's jishinmei (mei he cut himself). We can tell this from close study of the strokes. Shinkai took over the responsibility of his father's (Shodai Kunisada) mei in 1645. So, we can date the sword to the time period of 1623-1645. For more information about the study of Shodai Kunisada's mei, please see our article here.

Izumi no kami Kunisada is one of 21 smiths ranked as O-wazamomo by the Yamada family of sword testers. The criteria to achieve this ranking is that 7-8 out of 10 tested blades by a given smith had to perform at the o-kiremono level. The meaning of o-kiremono is that the blade cut through the central chest of an adult male completely and with ease. Works by O-wazamono makers are celebrated for their outstanding achievement in executing the functional purpose of a blade.

This blade is in full polish and it has no kizu. The polish has a few light scratches as shown in the photos and there is some running hada inside the bo-hi. There is no coarse hada or ware in the ji or ha and the entire work shows excellent control in both the kitae and tempering. This comes with a NBTHK Tokubetsu Hozon paper. Generally, a shinto blade that is machi-o-kuri can not get a Tokubetsu Hozon paper. The fact that this sword was awarded one speaks clearly to the quality of the blade and the importance of the mei. The double habaki has a solid silver base with a gold foil over silver outer panel. The dark color of the silver in the photo below is from natural tarnish. This katana also comes with a recently made (in Japan) shira-saya and a silk storage bag. A long zaimei Tokubetsu Hozon katana by the Jo Jo Saku co-founder of the Osaka shinto tradition.
