Some people say that the concentric circles on the hilt of Gou Jian's sword could not be copied at that time. Is it true?

The sword of Gou Jian, the King of Yue, which was unearthed in the No.1 Tomb of Wangshan, jiangling county, Hubei Province in 1965, is a national first-class cultural relic. It is 55.7 cm high, 4.6 cm wide, 8.4 cm long with a handle and weighs 875 grams. Its body is extremely sharp, and it is engraved with? Gao Wang's dove is shallow, so why use it at first sight? Eight characters.

When this sword was unearthed, it immediately caused a sensation all over the world. After more than 2,4 years, this sword is still chilly and extremely sharp, with clear grain and no rust to follow. The front of the sword lattice is inlaid with blue glass, and the back is inlaid with turquoise, and there are eleven concentric circles with an amazing interval of only .2 mm cast in the hilt. It is hard to believe that this is a casting process more than 2, years ago.

When archaeologists made an in-depth study of Gou Jian Jian's sword, they found that there were still many amazing things about Gou Jian's sword. Many contemporary sword-casting masters tried to copy this sword, but there were indeed many problems before them, such as the different proportions of copper, tin, iron, lead, sulfur and other components on the same sword, how to make the diamond pattern on the sword, and how to deal with the anti-corrosion of the whole sword to achieve the effect of a real sword.

It has to be said that it is impossible to copy an identical sword of Gou Jian, the King of Yue, without the help of modern technology. At least no one in the world can reach this level at present, but if you are willing to invest time and financial resources in research, you will definitely make a breakthrough, and you can even cast a simulated sword comparable to Gou Jian's sword, such as Xu Guangguo, the most authoritative sword casting master in China.

Xu Guangguo spent 14 years to decipher the secret of Gou Jian's sword, and he was determined to restore the history and the essence of Gou Jian's sword. In the end, he successfully overcame most of the problems and created a high imitation sword. The high imitation sword made by Xu Guangguo has been unanimously affirmed by experts at home and abroad, and the degree of simulation is very high. Therefore, Xu Guangguo's research on Gou Jian's sword is the top in China, so his research on Gou Jian's sword is the best in China.

According to him, the technology of concentric circles on the hilt can be achieved by modern lathe technology, but it will be too modern when it is used to copy Gou Jian's sword of Yue King more than 2, years ago. Therefore, when he copied Gou Jian's sword, he resolutely gave up using modern technology and cast the eleven concentric circles by hand. After hundreds of transformations, Xu Guangguo successfully cast the eleven concentric circles. Although the depth and width of the eleven concentric circles of Xu Guangguo's simulated sword are inconsistent, it is worth noting that the smallest interval between the eleven concentric circles he cast is only .1 mm, which is finer than the .2 mm on the real sword!

That is to say, if we modern people are willing to devote our energy to research, it is not difficult to build a high imitation sword that can rival the sword of Gou Jian, the king of Yue, by hand. The only difficulty is that modern people are impetuous and confused by utilitarian heart. Many people say that the ancient sword-casting technology has been lost, and it is impossible to copy an identical sword. I agree with this myself, and who is willing to spend a lot of time on this seemingly meaningless thing? It is not what modern people like to do to invest a lot and get less return. But as I said, if you really make up your mind to do it, it is still possible to build a simulated sword comparable to Gou Jian's. The hard part is that no one wants to do it.

Just like Xu Guangguo studied Gou Jian's sword at the beginning, he did it alone without help and at great risk of losing everything.
