This has been realized by having so-called functionally-gradated structure that the cutting edge is hard, and the hardness is gradually decreased to the core, which makes compressive residual stress generate at the cutting edge. Because saving trouble even a little makes this compatibility balance lost.Īlso, 'sharply cut' and 'not break' are difficult to be compatible. In the modern metallurgy, 'not break and not bend' is called 'compatibility of strength and tenacity' and improvement research of structural material has still being done night and day. It is thought that the process of creation of Katana has been developed basically in order to achieve three conflicting natures, 'Not to break, not bend, and sharply cut' simultaneously. Although the main point of A poem About the Katana' is to lament that books already lost in China still exist in Japan, and not about Katana, it shows that the beauty of Katana was already recognized by overseas curiosos from the late Heian period to the early Kamakura period as one of Japan's exports. This poem describes a merchant of Yueh (South China) who goes to Japan to buy Katana already being called treasure swords given their artistic qualities found in the fittings and appearance. Katana is found in a poem titled 'A Poem About the Katana' by Ou-yang Hsui in Baisong. Katana is not only a Weapon, but also an Art-craftĭifferent from swords of other countries, the biggest feature of Katana is that the body of blade itself has artistic value, aside from the fittings (Koshirae). The Nakago has holes (Mekugi holes) to fix the body of blade to the Tsuka (handle) with pin fasteners. They feature a process of folding and forging' two types of metal, hard brittle steel and soft iron, so the Toshin (body of blade) and Nakago (core) are combined together. They also functioned as a support pillar of spiritual culture, 'the very soul of the samurai against the backdrop of the military government. Old and unbroken lines, including the Imperial family and shrines, value treasure swords (such as Amenomurakumono tsurugi) as a proof of power. Its beautiful shape has symbolic meaning as well as its use as a weapon since ancient times, and many are highly appraised as art objects. Craftsmen who make Katana are called 'Toko (sword craftsman),' 'Tosho (sword master)' or 'Katana kaji (swordsmith). They are classified as Katana (Tachi, Uchigatana), Wakizashi and Tanto depending on size. Katana (Samurai Sword) is a generic term for swords forged in the originally developed way in Japan.
