The early swords, which were originally only more than ten centimeters long, had a straight ridge and two blades, a flat and broad sword body, and a handle that was sandwiched with wood chips, and had no sword grid, and then developed a fixed shape, mainly composed of two parts, the sword body and the sword stem, each part with a name.

The front end of the sword body is called "Feng", the convex midline of the sword body is called "ridge", the two sides of the ridge are sloped and called "from", the blade from the outside is called "Gong", and the spine and the two are "wax". The handle of the sword is called the "stem". There are two main types of stems: flat and round. Between the stem and the body, there is a "grid" with a gauntlet, also known as "guard".

The end of the stem often has a round "head" or "root". On the stems there are round "hoops". The stem is often wound with rope, the rope is called "箑", the ring at the end of the hilt is called Duo, the scabbard is also called "room", and the short sword is also called "dagger".

The head and grid of the sword are often made of jade, and this kind of sword is generally called "jade sword". In the coming years, the shape of this sword gradually matured and became active on the battlefield as a basic weapon for infantry.

Luo Chen felt the evolution of the sword, and slowly became less repulsive to the sword

Human beings vary in size and length, and different swords are chosen not for the sake of beauty, but to make them suitable for their own use. Therefore, it is divided into a third-class sword system, so as to suit the third-class sword-bearer, and whoever uses what sword is at his own convenience.

The hilt of the sword is five inches long, and if the sword body is five times the hilt, then it should be three feet, weighing nine pounds, that is, three catties and twelve taels. Only tall and powerful swordsmen can wear them, so it is called the sergeant system.

The body of the sword is four times the hilt of the sword, so the length of the sword is two feet five inches, and the weight is seven pounds, that is, two catties and fourteen taels. It is suitable for people of ordinary stature and strength, so it is called the sergeant's system.

If the sword body is only three times the length of the hilt, it is only two feet, and the weight is only five pounds, then it only weighs two catties and one or two or three points, light and short, called the lower system, and it is suitable for those who are short and weak.

Luo Chen estimated that he was of ordinary stature, almost a sergeant

So the sword you should use is two feet five?

The Diamond Sutra is not in a hurry to teach Luo Chen to practice swords, and he is crazy about history, and Luo Chen is very satisfied with what he hears and watches.

To be honest, this situation is a bit pitiful, which master teaches the use of a sword, and he won't pull this!

Just talk about these things with Ling Yu's study

"Boy, don't underestimate this step, if you don't understand this, you won't be able to feel the connotation of the sword, and you won't be able to exert the true power of the sword."

When the Diamond Sutra is explained, it is another interjection lesson.

Luo Chen, hehehe, you're right, I'm listening to it and watching it.

The Diamond Sutra continues.

The use of the sword, not only for killing, but also for scribe jewelry, but after all, it is mainly to defend oneself against the enemy, such as the sword is too long to use inconveniently, the short sword is difficult and far, the sword is too short and has no striking power, the long sword is heavy and slow to swing, both are not suitable for practicality.

Luo Chen, what do I use, except for the long sword and short sword, there are other things, don't complain.

Finally, after the explanation of the Diamond Sutra, Luo Chen gained a lot of knowledge of swords.

Then, the Diamond Sutra introduces many types of swords.

At this time, the Diamond Sutra asked Luo Chen what kind of sword he wanted to choose.

Luo Chen pondered slightly.

Meridian Mandarin Duck Sword: , a type of double sword.

The sword is three feet long, the sword body is flat, the lower part is one and a half inches wide, the upper part is eight inches wide, the two sides of the sword body are pointed swords that are inclined upward, the muddy body is like a saw blade, the tip of the two swords is in different forms, one is a semi-circular ring, such as a crescent moon, and the crescent tip is outward; Although the other is also crescent-shaped, there is a protruding spear-shaped spear head in the middle of it, the sword handle is flat, the cloth belt is tied on it, there is a disc iron gauntlet on the sword handle, there is a crescent-shaped gauntlet on one side of the sword handle, which is thin and sharp, and there are double-prismatic spear thorns at the end of the sword handle, and this weapon has blades on all sides, which is very sharp.

didn't have any special thoughts, Luo Chen felt that this meridian mandarin duck sword was quite eye-catching.

"Okay, take the sword."

The Diamond Sutra was pounded, and a pair of three-foot long swords were thrown to Luo Chen.

"We're pressed for time! Let's start practicing your sword now! ”
