2. History of samurai swords development

The form of Japanese swords has changed a lot from the late Heian period, through Kamakura, the Northern and Southern Dynasties, Muromachi, Azuchi-Momoyama, the early Edo period, the middle period, and the end of the Shogunate. The straight Katana sword is suitable for stabbing, and the curved sword is suitable for swinging and chopping. The reason for such a change is mainly caused by the change of the fighting style, and the knives were improved continuously from the end of Heian period to fit for immediate fighting.

From the late Heian period to the Kamakura period, there were five major centers of Japanese sword making: Yamato, Bizen, Yamashiro, Sagami, and Mino, and there were many famous craftsmen.

Iron swords were made in the middle of the Kugun era (200-771) in Japan, and the raw material was mainly iron. The swords made before the end of the Heian period were classified as epic swords, and the shape of the swords differed from the common Japanese swords of today, either with a straight edge or with a double blade. The ancient swords are extremely rare and are important archaeological materials.

The characteristics of the Heian period tachi swords are: Ho-zukuri, Umidori, small cut first, kyo reverse, narrow in front and wide in the back, and beautiful blade shape.

The early Kamakura period Japanese swords were similar to the late Heian period, and the establishment of the martial political system of the Kamakura shogunate made the sword world very active. Emperor Hou Toba even set up the Goban forge and called the swordsmen to forge swords every month to actively encourage sword making. In the middle of Kamakura period, as a result of the emphasis on usability, the blade was wide and the overall width varied little. The blade of the knife was the first to cut the head of a pig, and the quality of the knife was really strong and robust. At this time, the production of short knives began to prosper. At the end of the Kamakura period, the social turmoil brought by the two invasions of the Yuan army and the collapse of the original political system made the sword-making industry prosperous. The Japanese swords of this period were more bold than those of the mid-Kamakura period. It inherited and developed the characteristics of wide blade width and small variation of blade width, and the cut first was longer. Short swords, Katana, and Tachi also appear longer than other periods.

During the Northern and Southern Dynasties, large swords called Dachi and Nodachi appeared in large numbers, which were different from the previous ones.

After the middle of the Muromachi period, the Japanese sword changed from the tachi, which was worn with the blade downward, to the katana, which was worn with the blade upward.

In the Edo period, the forging industry flourished throughout Edo (present-day Tokyo) and Osaka, and famous swordsmen emerged from all over the region. As the period of peace and prosperity continued, samurai swords began to blindly pursue flashy blade text and gradually departed from the essence of practicality. In addition, the decorations of knives such as tsuba, small shank, Megan, and matsu began to develop in this era.
