"Oxtail Knife" is a standard weapon equipped by government officials in China in the late Qing Dynasty. It is named after its oblique body, which looks like oxtail.

In fact, the oxtail knife in real history appeared in the late Qing Dynasty.

Now it is not only used by martial arts lovers to practice martial arts, but also becomes the representative image of ancient China Dao in almost all comics and film and television works.

Oxtail Dao, with wide and thin blade, light handle, easy to carry and effortless to dance, looks more intimidating than Yanling Dao and Shun Dao.

The wide and thin blade of oxtail knife makes the whole center of gravity move backward, making chopping more convenient and powerful. In addition, the tip of oxtail knife is thinner, which is more likely to cause wounds on soft objects and leave deep scars. However, this blade design is not ideal for hard objects, bones and armor. Then the overall evaluation is that the flesh is weak.

However, as an official and Jianghu escort in the late Qing Dynasty, there were not many opportunities to face armor, and the design of oxtail knife was more than enough.
