Li Mengxi needs to forge again.

The incident happened to Jian Yong. Jian Yong wanted a hook sword and asked for it. We were all good friends and there was no reason to refuse.

Li Mengxi needed to build a hook sword specially for Jian Yong. Not only did it have to be successful, but it also had to be of high quality.

The problem lies here. Li Mengxi knows the steel filling method, knows the difference between steel and iron, and knows how to perform heat treatment, but he has no practical experience.

Li Mengxi summoned a team of blacksmiths and asked them to select iron first, while he himself was thinking about how to make a hook sword.

The Hook Sword is not intended to be used as a serious weapon at all. The only purpose of the Hook Sword is to be equipped to "Jing Ke", that is, to be equipped to our envoys, so that in case something changes during the banquet, the envoy's left hand

He drew his hook sword to block and defend for two seconds, then drew a dart with his right hand and flew out towards the enemy's leader.

The only purpose of making a hook sword is this. In fact, the hook sword is not a sword, but a shield. The reason why the messenger is allowed to use the hook sword instead of the shield is because it is too illegal for the messenger to carry a shield to a banquet.

Peace.

Now, Jian Yong has taken a fancy to the hook sword and wants to use it as a weapon. This puts Li Mengxi in a dilemma. He needs to improve the weapon that was just a rough design into one that can block, fight and can be used in actual combat.

sharp weapon.

He took out a piece of paper and drew the pattern of a hook sword based on his impression. After drawing the pattern, Li Mengxi frowned and thought about the technical details of making a hook sword.

Use the control variable method to explore what variables are there for a weapon?

Weight, length, shape, center of gravity, portability, lethality.

Considering Jian Yong's needs, Jian Yong planned to use hook swords to replace the three-foot swords worn by ordinary scholars. This required that the hook swords should be as light as ordinary swords.

In terms of length, the hook sword is a sword used for blocking. To block, the length must be advantageous. This requires that the hook sword should be one section longer than the ordinary sword.

In terms of shape, the hook sword is just a hook, without any special improvements. When Li Mengxi looked at the drawing carefully, he stared at the hook of the hook sword for a long time, and he suddenly realized that the hook sword seemed to only be able to kill with a hook, but

There is simply no stabbing ability of ordinary swords. For swords, stabbing is always faster than other attacks. So, what about adding a sword tip? Li Mengxi seems to have realized something.

He took a pen and drew on the drawing, and added a sharp tip to the curved hook of the hook sword. After adding a small tip as long as a finger, the hook sword could be used for assassination immediately, and its practicality was immediately greatly enhanced. That simply

Just add it.

In terms of the center of gravity, based on the long-term exploration of weapons, it is known that the closer the center of gravity of a weapon is to the hand, the better it can be controlled. In order to balance the center of gravity, weapons are forged with thickened grips, added counterweights, or thinned blades, etc.

Various operations. In view of the complicated shape of the hook sword body, it is difficult to balance the center of gravity so that the center of gravity is close to the handle. Therefore, counterweights can be added, heavier copper can be used to make the handle, and gold and silver can even be used.

In terms of portability, since the hook sword is a substitute for a single sword, it should not be too heavy. The single sword is a self-defense weapon and is used to quickly draw out to defend against danger. Therefore, the hook sword must be retrieved quickly and cannot be a drag. Think again.

Due to the complicated shape of the hook sword, the hook sword cannot be scabbarded. Moreover, in order to secure the hook sword with a complex shape and make it accessible quickly, carrying tools is the most important thing.

Li Mengxi looked back and saw that the messenger was waiting behind him in boredom. Li Mengxi waved to the messenger, "Go and call the embroidery lady Liu to come."

After a while, Mrs. Liu came. Li Mengxi didn't care whether Mrs. Liu could understand or not. He took the drawing and talked with Mrs. Liu about his ideas. Anyway, Mrs. Liu was well-informed and experienced in sewing.

You may have a good idea.

"Well, I'll give you some leather, and you can find someone to show you how to make it nice, convenient, and strong.

If you do it well, you will be rewarded heavily." Li Mengxi explained.

Speaking of heavy rewards, this means that it is another important military task, and if it is done well, at least how many kilograms of food can each person get.

After taking Li Mengxi's warrant, Liu went to the branch area for leather and cloth.

Soon, the craftsmen selected the iron and came over to ask Li Mengxi when he would start work.

Li Mengxi passed the drawings around to everyone for review. He stated many requirements for the creation, including strict requirements in terms of shape, weight, center of gravity, etc. After explaining, he ordered the blacksmiths to build it.

There were as many as twenty-four craftsmen recruited by Li Mengxi to make hook swords. They were divided into eight groups based on three people, and eight samples could be made at the same time.

It can be seen that Li Mengxi is preparing to solve the problem violently again. The preparation is to use testing methods to measure the best sword shape. There is no way. Building weapons requires experience, and Li Mengxi has no experience, so he can only use experiments

way to explore.

Following Li Mengxi's orders, the blacksmiths melted the iron two hours later, fused the pig iron and wrought iron, and poured them into molten steel. Following Li Mengxi's instructions, they divided the molten steel into twenty pots and prepared to adjust the steel properties later.

Using the remaining molten steel, the blacksmiths made eight rough embryos of hook swords and showed them to Li Mengxi.

Regardless of the appearance of the finished product created by the craftsman, the shape is generally correct.

Someone took a three-foot stainless steel sword and compared it with eight samples one by one. It was found that each of the eight hook swords was indeed longer than the three-foot sword, but some were longer than a palm.

Some are less than an inch long.

The first question comes. It is known that the longer the hook sword is, the easier it is to hook the enemy's weapon first. So what is the appropriate length of the hook sword?

Li Mengxi decided to give it a try.

He summoned 300 soldiers and ordered them to come forward to fight with the hook sword and the three-foot sword. After a long time, he collected the opinions of the 300 soldiers and asked which hook sword was the best.

Ninety percent of the soldiers agree that the longest weapon is the best to use.

That's right. One person's feeling may be biased, but as many as three hundred people's feelings are correct. Seriously, the longer the hook sword, the better it is to use.

But then there is another problem. After all, the hook sword is a self-defense weapon. If it is too long, it will be inconvenient to carry, and it will be awkward to pull it out in an emergency. Therefore, how to make it long enough without affecting convenience?

Gotta give it a try.

The craftsmen were asked to hang their hook swords on their waists, simulating various situations such as kneeling, sitting, standing, etc., according to the most inconvenient kneeling and sitting posture, according to the optimal distance that the hook sword handle can be grasped, the hook sword can be grasped by the hand, and the sword body

When placed on the waist, with this length and this carrying method, if a person with a height of seven feet kneels down, when the hook sword is longer than four feet, the tail of the sword will hang to the ground, which is inconvenient.

Therefore, the limit length of the hook sword is established. If the hook sword is light, it cannot exceed four feet.

Taking the middle value, a hook sword with a length of three feet, seven or eight feet is the best.

The rest is to refine the details, the angle of the hook blade, the size of the hook blade, the size of the crescent of the hand guard, the length of the handle, the thickness of the handle, etc.

Li Mengxi had never made a hook sword before, and he didn't know any of the details of how to make a hook sword.

In order to finalize the most reasonable, sharp and scientific structure of the hook sword, he could only conduct large-scale testing.

In order to test the size of the hook blade, Li Mengxi assigned thirty kinds of hook blades of different sizes. The largest hook blades of these hook swords were shaped like a question mark, and the smallest ones were similar to the meat hooks used to kill pigs.

In terms of angle, the angle of the hook blade ranges from outward hooking, to gradually shrinking inward, to internal hooking, a total of fifty angles.

[To be honest, I have been using the Huanyuan app recently to read and catch up on updates. It allows me to switch between sources and read aloud with many sounds. .huanyuanapp is available for Android and Apple.]

There are also crescent hand guards. The length, distance, and crescent angle of the hand guard are each divided into twenty types.

Also, as for the handle, ordinary swords have a fusiform handle or a straight bar handle. Both handle shapes are comfortable to hold, but the straight bar shape is convenient for thrusting, and the fusiform shape is comfortable for turning. Compared with swords,

, the action of the hook sword may be more complex, so the fusiform hilt is more suitable, but this may not necessarily be the case, so hilts with different thicknesses and shapes must be made for testing.

Li Mengxi wanted to use testing to select the best hook sword structure. To test, a large number of samples were needed, and to test a large number of samples, a large number of blacksmiths were needed to help. Therefore, Li Mengxi summoned all the blacksmiths.

Because it is just testing the shape of the device, there is no need to test the strength for the time being, and because the shape test requires making a very fine shape, it is necessary to use the forging method to forge a hook blade with a curvature that differs by no more than five degrees, and it is difficult to hammer it with one hammer.

To achieve such precision, but using the casting method, take a mold from Huangnihu, use bamboo pieces to compare with the pattern, and trim the mold little by little. Not to mention a difference of five degrees, it can be made with a difference of one degree.

Molds have the natural advantage of processing delicate shapes.

Therefore, Li Mengxi decided to cast all the necessary shapes.

The entire blacksmith camp stopped working. All the blacksmiths put down their work and moved around to move debris around, and began to cast molds with living mud all over the ground.

After a few hours, the mold was not finished and it became dark.

Another day, the blacksmiths continued to make molds, while Li Mengxi prepared a lot of paper. He found a group of people with rulers to draw a lot of forms for later use.

Half a day later, when the blacksmiths finished the molds and started casting weapons, Li Mengxi and his men had already drawn a thick stack of forms.

After noon, the iron smelting and pouring work began in full swing in the blacksmith camp.

It is expected that in subsequent tests, hook swords made of cast iron will easily break due to strength issues, so a large number of spares will have to be made, at least dozens of each model.

It is known that the hook sword involves various variables such as the size of the hook blade, the angle of the hook blade, the guard, the shape and thickness of the hilt, etc. There are nearly two hundred types of various models, and twenty spares of each model are required, and four samples are required.

thousand.

If I hadn't bought a huge amount of iron from other places not long ago, I wouldn't have any use for it now.

The mold casting took another two days.

It took three days, and even the model of the device has not been finalized.

On the fourth day, four thousand cast iron hook swords were cast. Li Mengxi mobilized a large number of soldiers. He led the team out of the city and set up a huge formation in the open space outside the city to prepare for a massive test.

In the first round, measure the size of the hook blade.

There are forty kinds of samples. The forty kinds of hook swords are the same length and weight, and the center of gravity is also at the handle. Only the hook blades are different in size.

At the beginning of the test, there were two hundred soldiers in one group holding hook swords, and several hundred soldiers in one group holding other weapons.

In the first round of the test, one soldier came on stage holding the largest hook sword with a curved blade that looked like a question mark, and one soldier held a three-foot willow sword.

With an order, both sides attacked.

The two soldiers rushed together. The one with the wooden sword thrust straight at him with his sword, and the soldier with the hook sword used his hook blade to hook upwards.

When they met, although the hook sword successfully hooked the sword that was thrust straight at him, the sword still stabbed the man's shoulder.

Li Mengxi didn't understand fencing, nor did he understand what this duel could mean. He just honestly filled in the data from the test on the form.

The first data is that the hook sword with the largest hook blade stabbed the three-foot sword successfully. The hook sword successfully hooked the opponent's sword, but it was still injured.

After the first group of people are tested, the second group comes on stage again.
