The famed smith KANEMITSU 兼光 and it's genius pupils of smiths TOMOMITSU 倫光, YOSHIKAGE 義景, MOTOMITSU 基光 and the subject MASAMITSU 政光 - A legitimate school of OSAFUNE in Bizen province have been well known as called Soden-Bizen tradition that followed true Bizen tradition to adopt growing power from Soshu favor of outstanding Itame forging with rising quench method of rather stronger side Nie-based tempering. It is understood that Soden-Bizen school was born to meet with brave warriors' requirement during the disturbances of war in Nanbokucho age. The subject Katana is very heroically made and carefully forged to clearly indicate an extravagant Itame and Mokume marks against Midare-utsuri (irregular reflections) standing out clearly that is convincing strong feature of Soden-Bizen. There is a grain opening below Yokote ridge in front being eliminated by previous skilled polish. Nevertheless among similar works of Osafune, this katana is prominent and one of the most excellent conditioned OSAFUNE works over the 650 years of more.
