Previous answer is
　Kawachi Kami Kunisuke(the 2nd generation)
河内守国助（二代）

Special feature: Kawachi Kami Kunisuke is a son of 1st, and we have also 3rd, so sometimes he is called Naka(middle) Kawachi. He was so skilled he had ever made enormous number of swords in his life. He was very good at Choji-ba, so some people call him Shinto Ichimonji. Moreover, he made his original Choji, which looks like human fist, Kobushi-Choji, so he was also called as the same as his Choji name. He passed away on the 21th of August, Genroku 11.(1698).
