The back of the knife must be equipped with an iron ring. Why is the design of ancient broadsword so particular?

Machete, as the main melee weapon on the battlefield in ancient China, was one of the standard equipment for infantry in the historical period. After the replacement of dynasties, the form and style of pottery have been constantly evolving and improving. The difference between a knife and a sword is that its main means of attack are chopping and chopping. With what? Pick? 、? Sting? In contrast, knives are easier to use and more popular. As this question asks, we often see machetes with a row of iron rings on their backs in movies and TV plays. So what is this design concept? Generally speaking, the iron ring on the back of the knife increases the effect of cutting and gravity holding. When a person holds a machete upright, the iron ring will fall off and the center of gravity of the machete will shift to the direction of the hand, making it easier to operate the machete.

When a person cuts a machete, the iron ring will be thrown forward due to inertia, which increases the lethality of the machete. Of course, this is also based on the strength of machete users. There are many kinds of big ring knives, which can be roughly divided into three rings, seven rings and nine rings. Different people have different ring knives according to the user's mastery and wrist strength. Generally speaking, a sword is heavier than a sword, with a large handle and a thick blade. Therefore, after cutting the human body, the knife is likely to be too deep to be pulled out, especially when shopping with people, which is very fatal.

Therefore, these rings can help users to establish a stress point on the knife. When the blade can't be pulled out, it is much more effective to pull the handle by hand. However, if we study the history of the big ring knife more carefully, we will find that there are few descriptions of the big ring knife in ancient literature. There is no such knife in the official military organization, so most of the big ring knives we see are privately made weapons. According to the only information available at present, the knife around the island can only be traced back to the Qing Dynasty, and it was not recorded in the previous generation. On the contrary, in modern and contemporary martial arts novels, stories and other literary works, you can often see the figure around the island. Therefore, I personally think that the value of folk products around the island should be closer to the people, rather than killing the enemy on the battlefield.

? We all know that users will make a very clear and loud ring sound on the back of the big ring knife when playing it. ?
