History of the Katana
Throughout the history of Japan, fighting techniques changed, and thus the swords also changed shape. There are several types of katana, they were made to adapt to the samurai wielding it. But there are 4 periods in which the swords underwent major changes.
Jokoto – During the Jokoto period (800 A.D.), the swords used were straight, with a single edge (the Chokuto) or double (Ken) and poorly tempered. There was no standard design and they were tied to the waist by means of cords.
Koto (1596-1624)- In the Heian Period, the change in fighting style created the need to change the sword. Battles were no longer fought on foot, but on horseback. The swords became long, curved, with a wider and stronger base and a very fine tip. Before, Japanese swords were called Tachi, only in the Muromachi period did the classic Katana emerge.
Shinto (1596-1624) – During the Tokugawa government, with more accessible raw materials and the exchange of experience, the swords were even more refined, even with the existence of firearms. This period was harsh, as the use of swords and weapons was prohibited.
Gendaito (1876-1953) – In the Meiji Era, the swords were made for Japanese military officials, for rituals and public occasions. Although they had the same shapes as a traditional sword, they lacked the main characteristics of craftsmanship (handmade) and non-industrial steel.
