Lot Essay
This smith is listed in Iida Kazuo, Toko soran, as Shichirouemon (no) Jo Morihiro. There is a misprint in the book; the kanji for "hiro" is incorrect as listed and should be the same kanji as used by Soshu Hiromitsu. This smith changed his name from Shichirouemon to Shichirosaemon in approximately Kanei 8, the year this blade was made; because of the similarity of the kanji of "U" and "Sa", it was originally thought that there was a misreading, but that has been proven wrong. See Fujishiro, vol. 2, p. 556, for a similar signature.
