Why is the katana known as the simplest and most scientific sword type in the world?

No need to talk so much nonsense, just an intuitive comparison can explain the problem. First of all, straight swords are very popular in Europe. Straight swords have strong piercing capabilities, but the scratch range is not enough, which means they cannot cut people wearing armor. The Mongolians are good at using scimitars. Because of the curvature, the stroke of one slash can be much longer than that of a straight sword. It is very practical for chopping ordinary people, but its ability to stab people is insufficient and it is not suitable for dealing with heavily armored units. The reason why Japanese swords are said to have advantages is because the blade is slightly curved and can be stabbed and slashed smoothly. It combines the functions of a machete and a straight sword, and is not as heavy as a machete. That is why Japanese swords are said to be simple, and then Japanese swords The mechanics are also relatively moderate, so the knife shape is scientific. There are many types of swords, each with its own purpose and invention background. It is just that the Japanese sword combines the advantages of most swords and does not have great disadvantages. There is no need to worry about the material and workmanship. Given the same material and workmanship, there is no doubt that Japanese knives are more comprehensive. Most people have watched too many movies and anime, and they feel that the swords are clanging against each other and blocking in various ways. How can it be like this in reality? As long as you avoid the other party's sword, the sword in your hand will be on your body immediately. Instead of fighting sword against sword, it is better to carry a shield. There are many excellent swords in the world. We cannot say that any sword is omnipotent. It just depends on its mechanical ability. The design of Japanese swords comes from Tang swords, which is not very bad. I am also drunk when it comes to Damascus knives. The real technology of Damascus knives has been lost long ago. Nowadays, steel with the same texture and special texture is called Damascus steel.
