Look at the Xiuchun knife to cut the opponent’s knife with a knife. There are similar bridges in the Rurouni Kenshin movie, and Hu Che was also chopped. Is it true that ancient cold weapons always open their mouths? If you use the current metal craftsmanship What kind of metal should be the most suitable metal for cold weapons, tungsten steel? Boron steel? Manganese steel? Chrome steel? Can the weapon made out of it be able to achieve the existence of a nightmare for other cold weapons?
The knives made of modern steel can be placed in ancient times. They are first-class magic weapons. Even the most common spring steel knife can easily cut a gap out of the ancient treasure knives. But if you want to be truly invincible, and slashing with other knives can be crushed like cutting tofu, then I am sorry that you can’t do it, and this kind of material does not exist in the world. The two factors that determine the performance of a tool are toughness and hardness. The higher the hardness, the less likely it is to roll the blade, but it is easy to chip or break. Conversely, the higher the toughness, the less likely it is to chip, but it will roll and bend. Attributes have upper limits. The higher the hardness, the worse the toughness. Therefore, no matter how good the material is, it is nothing more than looking for a balance between toughness and hardness. It is impossible to achieve infinite hardness and infinite toughness at the same time. In addition, the sharper the knife, the thinner the blade, and the thinner the less durable it is. If you want to be durable, you can’t sharpen it too sharply. Look at the machete for cutting big bones and the knife for sashimi. It is impossible to cut iron as mud and blow it decisively at the same time. Just like you can’t ask a person to be fat and thin. And the knife is designed to slash people, not to slash. A good knife can cut a person in half. There is no need to seek to cut the opponent’s knife. The masters of the cold weapon era are not like ping-pong-pong as a martial arts drama. Time, if you don’t cut me with one cut, I will be cut to death with one cut.
