In many costume dramas, the figure of the sword will appear. Those who kill decisively, or heroes who wander the rivers and lakes, they will have a precious sword in their hands. When they fought with others, in addition to being superior in martial arts, the sword in their hands was far from being comparable to the enemy's weapons, and basically cut off the enemy's weapons at once.
Such a bridge section to see more, many people will believe it, and even sigh, the ancient sword can cut iron like mud, is this modern people will only create counterfeit and inferior, or the ancients are exaggerating? However, in costume dramas, the enemy's useful weapons will not always be made of tofu, so many people still feel that the current sword is far less good than in ancient times.
In fact, as a weapon, the sword was still relatively common in ancient times, especially in those generals with higher status, in addition to their own proficient weapons, they would carry a sword with them. For them, bulky spears and hammers are impossible to carry around, and the sword's easy-to-carry attributes make it possible to play a good self-defense effect in addition to showing identity and status.
So can the ancient sword cut iron like mud? In this regard, experts also said that in ancient times, it was possible to cut off other weapons with swords, but it was impossible to cut iron. Because the sword itself is only made of iron, if you want to cut iron, the current technical conditions cannot be reached, and the ancients are completely impossible. Then there is only one possibility, the ancient sword is not actually iron.
In fact, what many people do not know is that the frequency of copper use in ancient times is far greater than that of now, of course, the most common is the copper coin in ancient times. Here we need to popularize a basic common sense, that is, the higher the purity of copper, the lower the hardness will become. In ancient times, copper coins just used pure copper, and many small partners here did not find the problem.
Because in costume dramas, after a sword is cast, a copper coin is usually placed there to test whether the sword is sharp enough. I believe that such a scene can also be recalled. In fact, at this time, as long as the strength is in place, and the chopping technique is mastered, the copper coin will basically be broken.
However, the ancients were limited by the conditions, and there has always been a misunderstanding in the concept, thinking that iron and copper are very hard materials, and seeing that the sword cut off the copper coin, they naturally think that this is a good sword. In addition, when the iron was first developed, there were a large number of bronze weapons, and the sword cast with iron could naturally cut iron like mud, in fact, what was cut was not iron at all, but copper.
