Features: Gassan Sadakazu was a master swordsmith of Settsu Province. His personal name was Gassan Yagor\u014d. He was born in 1836 in Sukoshi Village, \u014cmi Province, and was adopted by Gassan Sadayoshi at the age of seven. He began his training around the age of eleven and is said to have mastered the distinctive ayasugi-hada by the age of twenty. Even after the Hait\u014drei (Sword Abolishment Edict) of 1876, he devoted himself entirely to swordmaking. In 1893, he exhibited a sword at the World’s Columbian Exposition in Chicago, where it received an award, and the following year one of his works was purchased by Emperor Meiji. In 1906, he was appointed an Imperial Household Artist (Teishitsu Gigei-in). He was also renowned as an outstanding engraver. Sadakazu passed away on July 11, 1918, at the age of eighty-four. His surviving works span from 1850, when he was fifteen years old, until the year of his death in 1918.<\/p>\n
