The pinnacle in the history of China's cold weapons-Tang Dynasty Cross Knife

tangdao, the collective name of Dao in Tang Dynasty, is the pinnacle in the history of ancient swords in China. The number of straight knives in the cavalry in Tang Dynasty is as high as 3%. The straight knives in Tang Dynasty are different from the ring-head knives in Han Dynasty. It has removed the ring at the tail of the ring-head knife and extended the short handle, and changed it into a long handle that can be used by both hands, so that it can play a greater role in the battlefield.

One of the biggest characteristics of tangdao is that it keeps its exquisite appearance, but it also greatly enhances the armor-piercing ability of the blade. Even an ordinary soldier can use it to exert good power.

Its blade is forged with 1-bar checkered steel, and the high-quality tangdao is made with Baotou steel. However, a finished product of tangdao has to be forged for dozens of times, so it was a terrible weapon armor in the Tang Dynasty at that time, which could not stop tangdao's sharp chopping.

In that dynasty, tangdao became the top weapon in the world at that time, combining the most advanced knife-making technology in the world. Therefore, the performance of tangdao was far superior to that of its contemporaries. Japanese aristocrats took possession of an imported China knife as a special honor, and even the Japanese emperor at that time was envious, admiring that the sword was still the best of China.

In the Tang Dynasty, the steel-clad technology adopted by tangdao was very advanced in the world at that time, which was different from the steel-clad technology we are talking about now. The difference between the steel-clad technology and the steel-clad technology is that one is hard to wrap and the other is soft to wrap. The steel-clad method is to wrap the steel outside the wrought iron with better flexibility and forge it together. The sword made by the steel-clad method has high hardness, which can be produced by chopping, and the blade is more flexible.

The ancients developed a famous heat treatment process, which is what we now call earth-covering burning blade. The earth-covering burning blade is to coat special materials on the parts other than the blade, heat and quench it together with the sword. At the moment of quenching, the exposed blade cools faster and becomes harder, while the earth-covering part cools slowly, thus keeping the blade body with better toughness.

Although the historical records and physical objects left by tangdao are extremely limited, this production technology and technique have continued to this day through continuous inheritance from generation to generation and deep excavation by modern craftsmen. It has become the most excellent production technology and sabre today, and its excellent quality has been widely recognized by sword collectors, and it is recognized as the pinnacle of China Dao.
