Tang Dao only looks at the shape, which seems simple, but somehow, it gives people the feeling that they can't get enough of it. As an official tool, the horizontal knife in the Tang Dynasty was used in a series of internal and external wars and martial arts examinations in the Tang Dynasty, which had a great influence on the development of weapons in later generations in China. It is not an exaggeration to call it a peak of ancient cold weapons in China.
The biggest feature of Tang Heng Dao is its narrow blade and slender body. Later, Japan introduced Tangdao and made a Japanese mountain city based on Tangdao, which inherited this point well. The main reason for the toughness of Tang Cross Knife is that it has been carefully polished by Baotou Steel. When grinding, it is made by folding method. The temperature of the fire needs to be controlled between 750 and 800 degrees, which is about 15 times. The fully folded Tang Cross Knife has 32,768 layers!
Then two pieces of steel with this thickness are stacked together, with mild steel sandwiched in the middle, heated to about 1300 degrees, repeatedly forged, so that the three pieces of steel are finally combined into one, and then slowly made into the length of the horizontal knife. Due to the high-temperature forging in the early stage, there is little carbon left in the blade body, so carburizing treatment is needed to increase the hardness of the horizontal knife. After tangdao covered the soil and burned the blade, the sharpness and toughness of the blade increased dramatically.
After that, it needs a little shaping, grinding, polishing and carving. In the early Tang Dynasty, this kind of Tang horizontal knife can only be rationed to the Royal Guards, and it is not unreasonable.
The emergence of these technologies makes the Tang cross knife different from any knife in the past and in the future. Compared with han dao, the beauty and toughness of Tang Cross Knife have been qualitatively improved, and it is more durable in actual combat. Compared with later Qing Dao, the elegance of Tang horizontal Dao is not possessed by other Dao. The reason why the Tang Dynasty horizontal knife was only popular in the Tang Dynasty is as follows.
First, the horizontal knife in the Tang Dynasty was too expensive, and many famous Tang Dynasty artists lost money to make a horizontal knife. Most people who buy Tang Dynasty horizontal knives directly use gold to calculate the price.
Second, some crafts have been lost. Although tangdao is popular all over the world, the status of craftsmen is low, and even if they are highly skilled, they are still regarded as tricks. These craftsmen are often controlled by the government and the flow of knives and skills is strictly controlled. Private craftsmen also follow the principle of spreading skills from the inside out. Coupled with the war in the middle and late Tang Dynasty, the spread of skills became more difficult. The national strength of the Tang Dynasty was not enough to support the creation of tangdao, so it was imperative to lose it.
Third, although Tang Heng Dao has many advantages and disadvantages in actual combat, it is not easy to carry because its blade is too straight. Japanese Shancheng changed it into a portable arc knife, while tangdao was classified as "Taidao". In addition, in the Ming Dynasty, the popularity of firearms gradually replaced this kind of Tang horizontal knife. Compared with the length advantage of Tang Heng Dao, it seems that firearms are more powerful. In addition, Tang's horizontal knife is too heavy to hold with one hand, which brings too much inconvenience to marching operations.
In any case, Tang Hengdao belongs to the essence of the Chinese nation and is a part of Chinese culture. It is still sought after by many fans. Only by maintaining the inheritance of culture can we ensure the inheritance of the Chinese nation.
