straight sword(tyokutou/tyokutou/tyokutou/tyokutou)
One of the ancient swords used from the late Kofun to Nara periods. As the name suggests, the blade has almost no warp and is either straight or slightly inward warped with a single edge. It is said to be the prototype of the Japanese sword, the “wanto (curved sword). The “wanto,” or curved blade, is said to be the prototype of the Japanese sword, and was widely made before it was introduced. Unlike the wanto, the shinogi, or “shinogi,” is the blade of the sword. Unlike the wanto, the shinogi (blade edge) is closer to the blade edge. A point on the side of the sword opposite the tip of the blade that is one step higher than the tip of the blade. It is also characterized by the lack of shinogi, which serves to strengthen the sword. A sword with a blade length of 60 cm or more is called a “big sword” (tachi), and a shorter one is called a “yokoto” (yoko-tachi). It is distinguished from the “tachi,” which is a large, warped sword with the same reading.
