Ancient Dao is called "the first of a hundred knives", and many treasure knives can cut iron like mud. It seems that this degree is the minimum standard of nod, in short, it is very sharp. In fact, this is only because modern people do not understand that the concepts of ancient iron and modern iron are different, and ancient iron and modern iron cannot be compared.
Iron in the ancient population mostly refers to pig iron, which has a very high carbon content and cannot be compared with steel now. The toughness and hardness of ancient "iron" are very poor. Nowadays, steel has low carbon content, strong toughness and high strength, and is widely used in daily life.
Therefore, in the ancient population, cutting iron was a kind of "special iron". Ancient iron not only contained iron, but also contained other impurities. In the process of cast iron, soft metals such as tin tweezers and copper are also doped, and the finally cast iron is actually not hard iron.
Besides, the ancient casting swords were forged by repeated beating. Under the condition of high temperature and high pressure, the impurities in the casting sword material are slowly removed.
Combined with the time, efforts and continuous forging of the sword casting teacher, you can also forge the raw iron treasure knife, and the texture of this treasure knife is different from other cast iron. It is also very easy to cut those cast irons with this kind of treasure knife with high toughness and hardness. It's like chopping watermelons in the market with a kitchen knife at home now.
Ancient famous knife
1. My kitchen knife: The kitchen knife used by famous chefs is made of the most common iron blade and the most common wooden handle. But because of my superb skills, even if I use it to solve cattle, it is "comfortable", so it won't take long to break, and the blade will be as good as new for decades.
Almost all knives are sharp weapons to kill people, but this knife promotes the Taoist classic way of keeping in good health. If you go with the flow, do nothing and do everything with the flow, then even ordinary things can be "comfortable" and benefit not the knife, but the person who uses it. My kitchen knife is the most unpretentious knife, but it is the most perfect knife.
2. The ancestor of Miao Dao: Miao Dao, a short knife. The knife is one foot two long and bends outward. The back of the knife bends with the blade, and there are two blood grooves and two stripe waveforms on both sides.
The blade is very sharp, and the handle is three to four inches long. It is made of two pieces of wood, horns or animal bones and fixed with pins. Chiyou, the leader of the ancient Sanmiao Jiuli Tribal Alliance, was named "the ancestor of Miaodao" by later generations and lost to Xuanyuanjian in the battle of deer.
