I think "Master Zhang" himself has answered this question and has been recommended and displayed. Very reasonable, very professional, and highly consistent with my cognition.

This kind of knife is generally called big ring knife. There are even long and fashionable names in romance novels, such as "Zijin thick back nine-ring flying wind knife". I also think that the broadsword of this design has three main purposes:

1. Increase the weight of the knife and strengthen the chopping power. As we all know, the greater the weight of the knife, the greater the potential energy brought by chopping. It may be difficult to cut a wooden stick pike with a single knife, but this broadsword with a thick back and a ring can produce potential energy close to that of an axe. If the user is strong enough, it is possible to directly cut off the opponent's weapon. Look at the picture carefully. Isn't Jet Li's single knife cut many cracks by the big ring knife? If you want to change a thinner sword, you will even be cut off.

2. Limit the chopping depth to avoid the blade penetrating into the body too deeply. Otherwise, it may get stuck in the enemy's body, and it is not convenient to pull it out immediately, which will affect the continued fighting.

3. Create momentum and take the initiative to deter the enemy. Just like Bruce Lee likes to make a baby before making a move, that's a tactic to disturb the opponent's mind. "Jingle" when showing off with a knife, "jump" when shaking and demonstrating, or "swish, swish, swish, swish, swish, swish, swish, swish, swish, swish, swish, swish, swish, swish In the fight, the sound of a rattlesnake attacking prey is chilling, or the noise of running annoys the opponent, which is of course beneficial to the knife owner.

However, whether it is history, movies or novels, there are few experts who actually use this weapon. Basically, they are uninhibited, fierce or ignorant people with great strength and just average martial arts. Often the appearance is to confirm the famous saying on the Internet that "the weirder the weapon, the faster it will die".

It is directly concluded that the main purpose of the iron ring on the back of the knife is to support X, which has no practical effect. In fact, there was no big circle knife in ancient times. This kind of knife with iron ring was invented by street performers in the late Qing Dynasty.

There are countless ancient sword weapons discovered in archaeology in China, but so far no big ring knife has been found. The earliest record of the Great Ring Knife is only in the Qing Dynasty, when it was used by street performers to perform acrobatics.

Because they found the iron ring on the back of the knife, it crackled when dancing, which was very bluffing and the performance was very good. Slowly, the juggler began to use the big ring knife. In street performances, volume is the most important.

But it is useless in actual combat, because it is not only useless, but also has many disadvantages.

First of all, the noise of the knife is too loud, and the enemy can easily find you, which won't work wonders. There was a loud noise when the camp was stolen during the war, and the enemy could hear it for miles. Isn't this death?

Secondly, it also increases the weight of the knife and is inconvenient to use.

Therefore, the big ring knife is used for juggling and has no practical use.

I am a craftsman who likes to study cold weapons. If you have any questions about cold weapons or swords, please invite me ~

There are many iron rings on the back of the ancient weapon big knife. Generally speaking, this broadsword is very heavy. The main purpose of the iron ring is to increase the chopping effect.

When the knife stands upright, the metal ring hangs down, and the center of gravity of the knife will shift to the direction of the hand as a whole, which is beneficial to controlling the knife.

When chopping, the metal ring is thrown forward by inertia, and the center of gravity of the knife will shift to the direction of the cutter head, increasing the chopping lethality.

The iron ring has another purpose: to limit the chopping depth. Because it is wide and heavy, once it is cut into the body, it is difficult to pull it out. The iron ring can let the extra kinetic energy push the other person's body back, you can cut it in and then the blade will come out with bullets.

Generally speaking, these functions. There were not many broadswords with iron rings in ancient times. First of all, they are very heavy. Second, the hoop was too loud and lost the chance of sneak attack. Sometimes using this weapon is a show-off: it means being aboveboard and never sneaking around. Do you believe that all the people who use big iron ring knives in TV dramas are heroes?

Our institute of cold weapons has just written an article on this matter, "What's the use of the ring on the big ring knife?" Why is it rarely recorded in the regular army and official history? 》

In fact, in addition to novels, storytelling and movies, there is also a big ring knife living in the world. The picture above shows the Great Ring Knife in Qing Dynasty. Let's look at the details.

It can be clearly seen that although the knife is rusty, its appearance is intact, its blade is straight, and it has no edge at all, not to say that the blade is rusty. In fact, many large ring knives left in the world are so uncut that there is nothing to increase their power. In fact, the big ring knife is not a real weapon at all, but is used for practice and performance. When practicing, you can judge your strength by the shaking sound of the ring. For the performance, the click of iron rings is more conducive to attracting the audience. After all, the communication in ancient times basically depended on roar, and when the broadsword was swung, the audience would follow the sound.

As for the four practical uses of the so-called knife ring on the Internet, they are all pure nonsense.

Inertia, adjust the center of gravity, increase the cutting lethality; (bullshit number one)

As long as anyone who has experience in weapon fighting knows, a sharp sword does not need to increase its power, and the human body is quite fragile compared with the sword. In fact, it doesn't take much effort, as long as it is cut, it is either dead or disabled. In particular, it is unnecessary to improve the attack power of the big ring knife, a wide-edged machete. It is to improve the hand speed to make it difficult for opponents to block or dodge, that is, to improve the hitting ability. After all, no matter how powerful the knife is, there is no point in cutting people. At the same time, if the power is too great and the knife is cut empty, it is difficult to recover the knife in time, which means that all the key points are exposed in front of the other party, and the flaw is too big. Not to mention that the ring on the back of the knife can only increase the change of center of gravity by a few centimeters, which has no effect. It's just that once the knife is cut empty, it will lead to the loss of the knife.

Take the lead and frighten the enemy (nonsense second)

The person who said this probably didn't even fight in groups, did he? Then pretend to be laughed to death by the other party, or be chased and hacked to death by the other party. ...

Decoration self-confidence, never stab in the back; (Article 3: Bullshit)

Civil fighting is life-and-death, so why bother mixing rivers and lakes? Never stab in the back? Why are you so decent as a young man?

Hook the ring to facilitate knife extraction; (Article 4: Bullshit)

Does the person who said this think that fighting is the chef cutting ribs? The real knife cutting does not completely chop the meat. The blade has a curvature. If you cut it, just drag it down and the blade will be drawn directly along the arc. Not only can the knife not be recovered, but it will also cause a bigger wound. When I drag it back, when I take the knife back, the tip of the knife is just forward, so I can take the next knife. So there is no need to install a ring to prevent the knife from cutting too deep.

Mainly to confuse the audience, put on a mighty look, make a mountain out of a molehill. Shangguan Jinhong used a big gold ring knife. Later, it was inconvenient to bring a big ring knife. Later, he picked two gold rings from the knife and practiced the dragon and phoenix double rings. Ranked above the knife, the cat is below the stick. Coincidentally, Shangguan Jinhong killed the cat with a dragon and phoenix double ring and won the first place in the world. He doesn't want to be attacked by a knife in the back. After Shangguan Jinhong's death, this knife wandered in the Jianghu for hundreds of years, and fell into the hands of Mongolian Lamaism at the end of the Song Dynasty. In teaching, it is regarded as sacred. Temujin unified the whole country, held a grand meeting with this knife as the award, and the golden wheel was the king of France. After using it, King Jinlun thought the gold ring on the back of the knife was better. King Jinlun took off the five rings on the back of the knife and trained them into five rings of gold, silver, copper, iron and tin. With these five rings, the Golden Wheel King dominated the world, and his martial arts were not under the five wonders of that time. After the death of Yang Guo, the king of the Golden Wheel, the Five Rings suddenly went public, moved westward with Mongolia, and were acquired by Pierre De Coubertin, the "father of the Olympics". He also couldn't put it down, taking the five rings as the symbol of the Olympic Games. After the popularity of the Olympic Games soared, Hitler was jealous and launched World War II to grab the five rings in Germany. In the war, France blocked the war with the five rings, and Hitler used them as the remaining two rings in the "war" and Temujin took them off and handed them down to future generations. Later, it was photographed as his logo by the "Double Ring" car. After the nine gold rings on the knife were removed, the knife was given to Guo Jing by Temujin. Later, this knife was recast together with the black iron sword sent by Yang Guo, and it became an artifact to slay dragons by relying on heaven, which can run wild in rivers and lakes and give orders to the world. Later, Tu Longdao was taken away by the Zoroastrianism King and passed on to his adopted son Zhang Wuji, the founder of Zoroastrianism. Zhang Wuji used this knife to fight against Yuan. Give this knife to Zhu Yuanzhang. With this knife, Zhu Yuanzhang defeated Yuan Chenggong, destroyed Chen Youliang and Zhang Shicheng, and ascended the throne. In order to prevent people from "leaning on the heavenly sword" for insurrection, Yu Hongwu issued a decree in the spring of the fifth year that Xu Da, Chang Yuchun and Aquamarine ordered 500,000 soldiers to force Emei Sect to hand over the heavenly sword under Emei Mountain. Emei school is a generation of women generals. In such a big event, they have to hand it over. These two cultural relics have never been seen by outsiders in the palace. During the Apocalypse, eunuchs made an insurrection, and the sword was stolen from the palace by eunuchs, and the sword was taken by Li Zicheng. Li Zicheng ordered millions of rebels to rise up and destroy Daming. However, this sword was acquired by Wu Sangui, the leader of Ning Guan fighters, and Eternal Sword was born together with Tu Longdao. Wu Sangui relied on the heavenly sword, assisted by the Eight Banners. Li Zicheng defeated Jiugong Mountain, so that the nod didn't fall into the hands of the Tatars. Before he died, he gave the "Dragon Slayer" to the four greatest guards, Hu Yidao Torre, and Hu Yidao Torre kept the "Dragon Slayer" to prevent the Tatars from following him. The Dragon Sword Slaughtered by Eternal Adversity was won by Miao Renfeng, the hero of Jianghu. The eternal sword was pinned down by the other side, so the golden-faced Buddha and flying fox in the snow-capped mountains also came to enter the dragon. The two swords are neck and neck, and they quit the Jianghu with their master. The Sword of the Eternal Famous was acquired by the League in the late Qing Dynasty, and the sword was dedicated to Sun Yat-sen. After Sun Yat-sen's death, the sword belonged to Chiang Kai-shek who founded the Imperial Military Academy and was distributed by cadets. And "Dragon Slayer Road" was later acquired by broadsword Wang Wu. After being destroyed, this broadsword was acquired by General Song, the commander of 29 army. The corona invaded and the mountains and rivers were broken. General Song reluctantly gave up "Tulong Island" and restarted the blast furnace. Tu Longdao was melted into countless broadswords by hardware donated by gangs, businessmen and overseas Chinese in Jianghu. 29 army officers and soldiers with one hand, the devil's head was cut off like a western claw. The devil is afraid of being cut off by a knife. Wen Xun of the Japanese army sent an iron collar to a Japanese soldier in China, but he couldn't stop the power of the broadsword team. The famous song "Chopping off the Devil's Head with a Big Sword" commemorates the fact that soldiers in 29 army have been handed down to this day, indicating that the Japanese army surrendered before taking off its collar after World War II. An iron chain was welded to the Japanese collar by the United States, and the head of the chain was buckled by the United States. Japan has become an American dog. Now we are gradually relaxing our vigilance and the chain is loose. We should always hold the broadsword. If Japan dares to bite us, we will cut off its dog's head rudely. "Eternal Tu Longdao" and "Eternal Tu Longdao" both achieved the same goal and made great contributions to the Anti-Japanese War. Isn't this providence? There were nine gold rings on the sword, but one was destroyed in World War II. Is this the sum of nine? Heaven dare not deliberately destroy one to prove that the full moon is indispensable and there is nothing perfect in the world?

What is the ring on the back of the big ring knife? Some people say it is used to increase the counterweight, while others say it is to prevent it from being cut into the meat and not being pulled out. Is it true?/You don't say. This is bullshit!

The big ring knife was rarely used as a standard weapon of the army in the past dynasties, but was generally used as a weapon of the people. Jianghu artists, masters guarding their homes, darts delivery guards and bandits looting houses all use this broadsword as a common weapon. Did you find a feature? By the way, these people are all pursuing a momentum. By creating momentum, jugglers can gather the audience faster; By creating momentum, the home-keeping teacher can scare away thieves with no effort; By building a strong guard, bandits who rob the road can stay at a respectful distance from others; By creating momentum, bandits can easily make the people in villages and towns feel scared.

Therefore, in order to achieve the purpose of creating momentum, eight or nine iron rings can be added to broadswords, iron rings or ringing iron rings will also be added to tridents, and similar things will be added to crescent shovel. In short, there should be momentum, so that people have a strong audio-visual feeling after listening to it.

Why isn't the ring of the big ring knife used to increase the matching? Because the blade of this big knife is actually very heavy, its back is five millimeters thin, and the back thickness of some knives can even reach one centimeter. It is difficult for a person to carry it with one hand for a long time, let alone fight with it. This kind of broadsword is usually worn by both hands, that is, it is used by both hands. It is completely useless to balance the weight of this broadsword with a few small iron rings, and it is completely unnecessary to balance the weight from the purpose of the broadsword.

So is it used to prevent it from being cut into pieces without being pulled out? What's more, it is impossible to cut the knife into the meat and not pull it out, unless the knife is too light and thin and stuck by the bone. The blade of this big ring knife is palm wide and heavy. If it is swung and cut into arms and legs, it must be split in two. Cutting into the body must be an incision like a child's mouth, so there will be no so-called wound to clamp the knife. The fact is that this rarely happens on other knives.

Seeing this problem, I went over it in my mind and found that this kind of weapon can't be found in my knowledge of ancient weapons. But in fact, this kind of weapon seems to be no stranger.

On second thought, I figured it out.

This kind of weapon does not exist in practical application, and the image of this iron ring knife in my mind comes entirely from the deductive story.

There are many iron rings on the back of ancient Chinese weapon knives, and their purpose is to "artistically process" this weapon.

Knife was advocated in ancient China. The predecessor of the knife can be traced back to ancient times, and the dagger made of stone mill is the predecessor of the knife.

Knife is also the most popular tool, which is different from all other cold weapons. Other cold weapons are specially used for fighting and war. Only the knife is actually the oldest living tool.

The essence of life tools is of course practical. Then all the development on the blade body should be practical for use.

But as the title suggests, we found many strange knives. What's the use of punching holes in the back of the broadsword and attaching iron rings?

On modern kitchen knives, we do see a hole in the back of the knife, and some western-style knives also open some holes in the blade. That's because these holes are scientific. The hole on the back of the knife is convenient for the knife to hang on the wall, and the hole on the blade is convenient for cutting vegetables, so as not to let the material stick to the knife.

But the ancient iron ring broadsword is of no practical use after thinking about it.

Among the dynasties most accustomed to using knives, whether it is the first knife in Han Dynasty, the iron knife in Eastern Jin Dynasty, the strange knife in Tang Dynasty or the phoenix-billed knife in Song Dynasty, only the phoenix-billed knife in Song Dynasty left a hole in the back of the knife.

At least before the Ming dynasty, there was no phenomenon of hanging iron rings on the back of the knife, and we couldn't see it when we looked up the history books.

Punching holes in the back of the knife and hanging an iron ring make the knife jingle, which is really useless except striking. Only artists rely on the sound of iron rings to attract the audience.

Because this kind of broadsword is really impractical.

So in actual use, we can't see this kind of multi-ring broadsword. At least in the formal establishment of the ancient army, there was no such broadsword.

The emergence of this broadsword is either a story interpretation or a folk artist. These two ways of appearance are out of the need of "artistic processing".

I have seen many people say that this hoop is just a show, but it is really not. This kind of knife is specially made, of course, only for civilian use. The ancient army would never use this weapon. This kind of knife is called the big ring knife, and the back of the big ring knife has a specially inlaid ring. Generally speaking, this kind of weapon is invisible in reality, so many people think that it may be used by the ancients for decoration and camouflage.

The unique shape of the big ring knife will leave a deep impression on people. This Dao is specially made by the people and is basically used by some Jianghu people. As for which dynasty the Great Ring Dao first appeared, there is no record in the history books. This kind of knife seems to have existed since the Qing Dynasty. Because it can't be verified, it is not certain that there was a big ring knife in the Qing Dynasty. Interestingly, the number of iron rings on the big ring knife is not fixed.

People with great strength may use nine rings or seven rings, people with little strength generally use six rings, and there have been records of using three iron rings. So what are these iron rings for? First of all, this hoop is loud to use. The user is showing that he is an aboveboard person and will never make a sneak attack. In ancient times, walking in the rivers and lakes was aboveboard.

The second and most important use is that when the knife is erected, the iron ring hangs down, and when the knife is swung out, the inertia force will be greater, which can increase the lethality. Of course, some martial arts experts have said that this kind of iron ring can't actually increase too much strength. On the other hand, if it is hollowed out, it cannot be recycled quickly, but it will increase the danger.

Generally speaking, the big ring knife was not common in ancient times, because it required a lot of users, at least with great strength, and secondly with martial arts, because brute force alone was far from enough.

In TV dramas and martial arts novels, there are often third-rate walk-ons who use the so-called "five tigers to break the door". These walk-on roles include, but are not limited to, giving the protagonist experience, venting his anger and providing the protagonist with better opportunities to pick up girls.

Pay attention to the observation, we can find that they have such a feature-that is, the weapon in their hands is really low, often a big knife, and there are several iron rings on the back of the knife to kill Matt. Don't mention how stupid it looks. It looks like a third-rate cannon fodder or a third-rate bit player.

Many people, influenced by romance novels and film and television dramas, really think that these weapons are made by beggars and third-rate bit players. In short, they are very low. This weapon should be invented by the editor himself. In fact, this weapon is really not a whimsical invention. Historically, this weapon has a famous name, called "Great Ring Knife". This kind of knife is often heavy and thick, especially on the back.

Contrary to martial arts novels, people who use this kind of broadsword are by no means shit third-rate masters. Such people are often first-class masters, and those beautiful and abnormal swords and daggers held by the small white-faced protagonists don't even have a chance to go through the motions in the hands of masters who can use big ring knives.

People who can use this broadsword will not like to make a fool of themselves. These people are very simple, so their weapons are full of practical aesthetics-this broadsword itself is very heavy, and the weight will be higher after being fitted with many iron rings. When these soldiers wield this broadsword, the huge gravitational potential energy will be converted into kinetic energy, which can become extremely terrible destructive power under the huge mass and inertia.

Moreover, it is worth mentioning that in romance martial arts novels, it often happens that when you gently hook the iron ring of this broadsword, it will be sold. This situation is completely an editor's brain hole. In fact, it can be said that it is almost impossible-the center of gravity of the big ring knife is forced to move all the centers of gravity of the big ring knife to the position close to the hand because of the existence of the iron ring. That may not be four or two kilos, but ten thousand kilos-it's a matter of arm strength and torque.

As for the noise caused by the banging of iron rings widely used in film and television dramas, it seems very careless. In fact, only fights in film and television dramas will be so particular. In reality, how do the two sides fight? In the process of chopping, can the sound of rushing interfere with the enemy? Will it be immoral? This all belongs to the problem that modern people eat too much. Ancient people never took it to heart. Cutting the opposite side is the first priority.

In the Qing dynasty, this kind of affordable weapon was widely used in escort agencies, and the escorts of escort agencies often carried this kind of big killer. When passing through a place suspected of being a mountain thief, you can shake this big ring knife first, listen to the voice of the mountain thief, and let them weigh whether the strength of the enemy is equal or not, which is also a great deterrent to them.

It is worth mentioning that this kind of big ring knife is also very practical, that is, portability. It is said that this broadsword should be difficult to carry, but it solves the problem. The carrying of this broadsword has a lot to do with this hoop-tie a rope to the hoop so that you can carry it on your back. After all, this big ring knife is not light in weight, and its shape is often rough and durable, so there is basically no overall sheath, so you can only choose to carry it on your back.

In ancient times, describing a person with superb martial arts would mean that he was proficient in all kinds of martial arts. The eighteen weapons here refer to the eighteen weapons in ancient times.

Of course, this does not mean that there were only 18 weapons in ancient times. Although it is the era of cold weapons, there are many kinds of weapons, and there are hundreds of them if they are carefully liquidated, plus hidden weapons.

Eighteen weapons generally refer to bows, crossbows, guns, clubs, knives, swords, spears, shields, axes, cymbals, halberds, shackles, whips, mallets, hammers, forks, palladium and knives. Only knives, guns, swords, sticks, spears and shields are common in the army because they are in line with their own advantages.

Then why are there so many iron rings on the back of the ancient Dao?

In fact, the iron ring on the back of the ancient big knife is just a kind of knife, called the big ring knife, which is used for step warfare. Not all broadswords have rings.

There are six, seven and nine iron rings on the back of the big ring knife, and of course there are other big ring knives. There are two opinions about the number of rings on the knife. One depends on the user's mood and preferences. Another view is to determine the number of rings according to his ability, because the number of rings will increase the weight of the blade, which depends on the individual's ability (I think this view is closer to the truth).

This is the difference in the number of rings on the knife. What is the reason for installing lifting rings?

There are the following aspects:

One is to increase chopping effect and power. Because the biggest difference between the use of knives and other weapons is the weight of knives, the general move of knives is chopping or chopping. So there is a requirement for weight, so one purpose of adding a ring is to increase its mass, which can increase inertia and increase the power when using it.

Of course, this will also increase the difficulty of its use, users have higher requirements for their own balance and arm strength, but it does not hinder people's love for it.

The second is to increase deterrence and have a deterrent effect. Generally, there are not many people who use the big ring knife, because the weight of the knife is beyond the control of ordinary people and the ring on the big ring knife will make a noise and it is not easy to be ambushed.

Therefore, people who use big ring knives are generally escorts and honest people (some simply like to use big ring knives). Walking like this will make a noise, tell him that you are armed and scare people like bandits.

But there is another kind of people who also like to use big ring knives, and that is Jianghu artists. You know, there were no speakers in ancient times, so they can bring their own sound function when they attract people's attention with big ring knives.

Third, it can limit the depth of cutting. This is due to the large weight and inertia of blades. Although you have increased your strength, if your knife is cut off, you can't get out. You can imagine the scene yourself. So the ring on the knife is a jam between the knife and the body, which makes the knife cut into the body to a limited depth and can be pulled out.

The fourth is modification. It is also said that one of the functions of adding rings is to modify the leaves, and we do not rule out this possibility. After all, there was such a thing as fashion in that dynasty.

Although it doesn't sound very convincing, the waist knife with ring is indeed more beautiful and attractive than the ordinary waist knife.
