Katana According to the form of war

The earliest shape of the Japanese knives, according to the modern archaeological community, is from the safe period of the knife of heaven, its works for the famous too small knife. Since then, after the Kamakura era, the Northern and Southern Dynasties, Muromachi era, An Tao peach mountain era, the development of the Edo period, the Japanese knife shape has become the style of today's people, which is also the length of the soil in the soil and the Edo period The period was prescribed.

According to the war form and the use of the development and change, the Japanese knife shape has gradually evolved. Its main performance for the Beijing anti-transfer from the stem, the waist reverse cut first advance. A lot of shape grow up heroic peace, the North and the South ancient knife also accepted the grinding and even large grinding on the treatment to shorten the length. In the Edo period, the main application of the Japanese knife is no longer a battlefield function and transformed into a fossil visualization of the performance tool, so the Edo period of the Japanese knife is also compared to the times before the sword is much weaker. 

Japanese knife production, from the late security to the Kamakura era, there have been large and prequel, prepared prequel, mountain city, phase of the state, the United States and the United States and so on and known as the "world five" system knife genre, and around the famous craftsmen. Especially for the former country's long boat town for Sheng.

Ancient times

Japan ancient grave era (200 years - 771 years) has appeared iron sword, when the raw materials to iron-based. For example, the mountains of the mountain and the island of the ancient mountain graves and the island with the ancient graves have iron sword unearthed. The "Golden Mile Iron Sword" unearthed from the mountain grave of the mountain is made in AD 471, which is for the purpose of commemorating the meritorious service of the emperor. The sword of this time has been rusted.

The sword before the end of the Heian period was classified as an ancient knife, knife shape is different from the common Japanese knife, or straight edge, or with a double front. Ancient knife is extremely rare, is an important archaeological materials.

Japanese knife from the Japanese native fern hand knives, belong to the Japanese original, the development process: fern hand knife (the end of the Yayoi era, the ancient grave era - the early days of peace) - hair plow hand knife - hair pull too knife - too knife - - too knife, knife, ribs, short knife.

7-8 century after the sword is relatively complete preservation, the famous four days of the temple of the gallbladder Lin Jian seven star sword, is the warehouse of gold and silver tin Zhuang Tang knife, some people think that these swords are mostly China, North Korea's exotic. Japan for China, the ancient impression is the deepest Tang Dynasty, so "Tang, Tang grass" and so on. And later as long as the overseas exotic, are known as the "Tang xx", but not specifically refers to China, for North Korea exotic, also known as "Tang" ╳ ╳, first, is the warehouse of the Tang knife, the knife from the The mainland, which is certain, but from China or North Korea is not known, so far no conclusion (of course, from the great possibility of China), and the Tang like a knife, refers to Japan in accordance with the exotic style to build the local Japanese knife. Then this is very clear, Tang knife knife non-Japanese products, Tang-like knife is a Japanese product, in the knife installed, the difference is very small, one of the differences for the Tang-like knife has a curvature, and Tang knife was a typical straight edge weapon. Tang knife is not a Japanese knife, in all likelihood is a Chinese knife Tang like a knife is wild knife, because knives to Tang Daodao line, hence the name "Tang like", but the knife is not straight edge, nor imitate the Tang Dynasty sword. In this era, Wu (the general name of the southeastern part of China) is considered to be the best knife (because the use of charcoal and other non-sulfur and other undesirable substances as a heat source, the Chinese imperial reunification, the use of custom equipment, began to use sulfide Of the coal, to facilitate the large number of manufacturing, so after the Southern Song Dynasty soldiers use the standard tool is not as good as the Japanese warrior knife. Special production of the sword is not necessarily, the number of knives in the number may not be less than the Japanese name, but only because of the traditional knife , Almost impossible to handed down.), This ancient emperor had poetry appreciation. At the same time a large number of foreign forging process inflows made Japan's forging level also increased significantly.

The number of swords that were left in the early days of the peace was rather scarce, and the raw materials were changed to slightly milled iron and steel, and the appearance remained sticky. Academic changes in the style of Japanese knives, and when Japan is how to create a unique machete and other questions, has not been fully explained. It is generally believed that the middle of the Heian period (around the 10th century) after the chaos and days after the chaos occurred, straight knife gradually turned into machete. At the same time, the production process is also changed from flat to similar diamond-shaped picks. The improvement of the craft makes the Japanese knife even stronger and sharper. The typical style of this transitional period is the "hair-shaped sword" made of the knife for the whole piece of iron, and the "small pills" knife with a two-blade structure and a curved knife, To the Ise Shrine of the Tibetan scriptures for the use of the original one of the most famous.
