Samurai Sword The structural strength
The sword has three elements, one is length, the other is flexibility, and the third is structural strength. Length is conducive to preemption and protection, flexibility is conducive to attack and strain, and structural strength determines the bending of the sword. The short sword is more flexible than the length of the sword. Therefore, in the spring and autumn period and warring states, where the sword has been established, the length of the sword is gradually lengthened. The lengthening method is to improve the body profile of the sword, and perhaps to cast the back and blade with different copper water containing tin, which can improve the strength of the sword and make the sword longer. Thus, the warring states had a bronze sword of 6 or 70 centimeters long, and in the peak of the western han dynasty, the record broke even more than 1.1 meters.
A straight and delicate sword is one of the hallmarks of Chinese martial arts, but in fact the symbol is less than 1,000 years old, and the time is much shorter.
As sword extend ceaselessly, the problem appeared, length can enhance sword attack advantage, but is decreased in close shot of original features, but more need to use the chopping, and growing more pressing needs professional chopping weapons cavalry. Therefore, the blade is more difficult to bend than the sword, and the manufacturing process is simpler. As for the sting function, the spear hand with the short knife hand tacit cooperation will be the sole professional.
The sword had put the knife in the end, but when the technology improved, the sword was in turn to put the sword in the corner. The sword lost its practical function, more and more to the decoration, to the elegant and lightweight transition, after entering the sui and tang dynasties, even officials rarely saber. But when developing to a certain stage, decorative covers aesthetic demand will function defect of the song dynasty military attache plaything dagger is proved, not to mention the modern and contemporary the decorated knives sword.
Sword, belong to double blade short soldier, have "a hundred blade of jun" reputation. The earliest sword appeared before the shang. During the spring and autumn period and warring states period, sword fighting and sword fighting flourished, and the theory of swordsmanship correspondingly developed. In the han dynasty, fencing was more popular, and many people became famous in the world. In the sui and tang dynasties, the sword was very delicate and magnificent, which greatly influenced the later generations, so it was called "the nose sword". After song dynasty, the wind of fencing was gradually replaced by sword dance. In ancient times, the sword was used for many purposes other than the weapon used as the weapon to kill. For one, the sword is used as a symbol of power and status. For example, "shang jian jian", which the emperor gave to his trusted ministers, had the power of life and death. Secondly, the sword is used as a legal instrument by the monk and the dao, saying that the sword can be "invisible", "the evil spirit", "kill the devil" and "take the first class in the thousand leagues". Third, the sword is used as a sign of status in etiquette.
