[ Highlight ] Swordsmith Master Shohei Miyairi (1913 - 1977), whose real name was Kenichi Miyairi, was born in Sakaki, Nagano Prefecture, and entered Kurihara Akihide's Japanese Swordsmithing School in 1937. He received many awards, including the Honour Prize at the Dai Nihon Tosho Kyokai Exhibition, the Prize of the Minister of Education, and five consecutive special prizes at the Exhibition of Created Sword Techniques. He later changed his name to Yukihira. He was one of the leading swordsmiths of the post-war period and trained his apprentices, and the name Miyairi is widely known as a master of modern swords. The signature 'Hon 3-piece forging' refers to a method of sword forging in which the blade iron and core iron are arranged vertically at the tip of the lever, and the skin metal is forged above and below the blade iron. Master Shohei studied under the swordsmiths Soshu Joko, Shizu Kaneuji and Minamoto Kiyomaro and used old iron and home-made steel to create swords using this three-piece forging method. This sword has the imposing style of Kiyomaro with a well made Koitame forging with itame grain with flowing skin and a wavy blade pattern that widens slightly towards the tip while keeping the waviness low, the nioi is bright and the blade is well attached nie, which is superb.
