This should start with the development history of cold weapons in China. Friends who are familiar with history may know, although? Sword? To some extent, this is China culture? Wu? But there was only one dynasty that really used swords on a large scale in combat: the Han Dynasty. In the early Han dynasty, swords were widely used as weapons of the Han army. Sword and shield corps? . But at that time, the armor rate of China's army was not very high. Double edge? Sword is obviously inferior? Single blade? Our knives are more practical. The latter can chop hard and cause damage, while the former is difficult. What about the sword in the late Eastern Han Dynasty? Just out of the battlefield, always carrying it? Ritual vessel? Face shows people.
But in the west, the sword has always been valued by the cold weapon war. As we all know, the armor of western soldiers has always been dominated by chain armor in the early days. The armor rate of soldiers has also remained high. In this case? Single blade? It is difficult to break through the defense of enemy armor by chopping. The sword, on the other hand, has the advantage that the knife can't have: straight stab. Soldiers can attack the gap between enemy armor by stabbing, causing death. Therefore, in the cold war in the west, the sword has never left the battlefield stage, but with the development of armor, it has been paid more and more attention. Later? Canned iron? At that time, many knights stabbed each other not only with swords, but also with daggers, otherwise they could not hurt the local armor at all.
To sum up, due to different degrees of attention, swords made in the West have a longer life than those made in China.
