Long Sword (Tachi) Inscription: “Made by Yoshiie” Yoshiie, the son or grandson of Munechika, is known for slim, classically elegant blades such as this, with its smallish point and its small irregular (ko-midare) hamon with small cloves (ko-chōji), and thick, subtle nie (visible martensite crystals) in the steel. It was an heirloom of the Shimazu lords of Satsuma, who received it from the sixth Tokugawa shogun.
