Kunisuke was one of the most well-known swordsmiths in Osaka during the early Edo period. There were three generations of Kunisuke in total. Since the second-gen was active between the first and the third-gen Kunisuke, he was also called Naka Kawachi (中河内). Kawachi is the short term of Kawachi no Kami, the honorable title given to this swordsmith, and Naka means the middle in Japanese.
He was famous for forging blades with the Kobushi Choji tempering line. Kobushi means fist in Japanese. This tempering line looks there are a lot of fists lining continuously. This blade has Kobushi Choji Hamon.
The first-gen Kunisuke was born in Ise province (today’s Mie province) and served Seki Kazumasa, the head of Kameyama Castle. However, after the Seki clan was destroyed, he moved to Kyoto. He became an apprentice of Horikawa Kunihiro, one of the most famous swordsmiths during the early Edo period. After Kunihiro deceased, Kunisuke learned the sword-forging technique from Echigo no Kami Kunitomo. Eventually, he moved to Osaka with Izumi no Kami Kunisada to become an independent sword maker in the seventh year of Kaenei (1630). It is said that he played an essential role in making Osaka Shinto movement. the superb craftsmanship of the first-gen was passed down to the second-gen Kunisuke.
The blades forged by the second-gen Kunisuke are categorized as Osaka Shinto. Shinto is Japanese Sword terminology that refers to the swords forged during 1596-1781. The blades made in the Osaka area during this period are called Osaka Shinto. There are many famous swordsmiths in this Osaka Shinto era. After Hideyoshi Toyotomi built Osaka castle, Osaka city flourished as a castle town and became the business center. Many swordsmiths moved to Osaka to look for better opportunities. They not only forged swords for those Samurai who lived in Osaka but also for feudal lords nationwide. Ikanshi Tadatsuna (Awataguchi Omi no Kami Tadatsuna), Inoue Shinkai, and Tsuda Sukehiro are the most famous among many swordsmiths.
One of the most notable characteristics of Osaka Shinto is its beauty in Jigane. Jigane is a visible steel surface pattern created by folding and hammering during the forging process), which made it possible by the location of Osaka. Osaka had close access to the Tamahagane (special carbon steel to make Japanese swords) production sites. The swordsmiths residing in Osaka were able to get high-quality carbon steel from these sites.
