Mark with Japanese mark: 壽矩 "Toshinori" | #433164

壽矩 "Toshinori". This mark comes from a "tsuba", a sword guard designed to protect the hand from contact with the blade and an opposing sword. It was made by Toshinori, who worked as a "soukenkinkou" in the Nara line of the Tanakatouryuusai house. Soukenkinkou is the Japanese name for metalworkers who design accessories for bladed weapons.
