東龍斉門人　渡邊寿光造　嘉永庚戌 "Touryusai monjin Watanabe Toshimitsu tsukuri Kaei kanoe inu". 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 Toshimitsu, 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.
