Jiangmen traditional casting sword

Someone imitated Cao Cao and made a meteorite dagger with special stripes. A sword that cuts iron like mud only needs good alloy, while a meteorite sword has the toughness of a sword that transcends the earth. Generally, it is tempered and folded to increase the toughness of the blade. Later, I made a bimetallic sword, but it was not as good as a meteorite after all. It has many rare metals. For example, in the scene of the movie Hero, the master of the State of Qin went against the sky and the sword could be folded to that extent in wartime, which is just an exaggeration of the movie and can't be done now. But the meteor sword can.

It must be noted that imitation and chasing after the wind only refer to style, and all this is well-founded.

Weapons that simply pursue hardness are not even as good as standard cold weapons. Bimetallic swords appeared in the Han Dynasty, which were generally made of pure copper (relatively speaking) and bronze, and later had iron swords. But do you know history? At that time, there was no turbine heating, even if coal was used, it could not reach the temperature needed for sword training or industrial ironmaking, and it needed to be folded several times, but this process was only to make up for the lack of temperature. Sword generally uses a variety of metals, even if there was only iron at that time, there were still fine iron and coarse iron.

About water, I agree with the one downstairs, and there is meteorite ice, but this is not a big problem.

CCTV has ten programs about meteor swords, in which the swordsmen in Longquan, after receiving the meteorites, could not melt them at a higher temperature than other iron mines, and finally made them with special chemicals. As for carbon strips, they pass through the atmosphere at a high temperature, but after smelting, will there be so much carbon?

Actually, people downstairs have been talking about knives. Knife requires higher hardness than toughness, while sword requires the opposite, so some things are not applicable.

As for the sword test, not only iron can be used to test, but now Japanese bamboo mats or bamboo leaves (traditionally) are used to test toughness and sharpness.

PS: Fiction is exaggerated, so it can't be used to compare reality.
