Sword of Light: Humanoid Self-Propelled Artillery

Chapter 110 Steel-Clip Forging Method
When Wang Gensheng handed the knife to the old blacksmith, the old blacksmith was immediately surprised:

"Steel clamp!"

Wang Gensheng was stunned by the old blacksmith's words.

"Master, this clamp steel! What kind of steel is it?"

The reason why Wang Gensheng took out Kuroshima Morita's royal sword to show the old blacksmith was mainly to ask the old blacksmith whether he could forge this kind of steel.

Of course, Wang Gensheng wanted the old blacksmith to make this kind of steel not to make a knife, but to make bulletproof steel plates.

After trying to use this steel knife to cut hair, Wang Gensheng suddenly had an idea. He used the knife as a target and fired a shot with a Type 38 rifle to test the strength of the blade.

But what Wang Gensheng didn't expect was that the blade, which looked only half a centimeter thick, could actually block the penetration of the Type 38 rifle bullet.

You should know that Wang Gensheng had tried it before. Ordinary steel could be penetrated by a single shot even if it was one centimeter thick. However, the blade of this knife was not penetrated. So Wang Gensheng wanted to ask the old blacksmith if he could replicate the steel used to forge this knife.

Because as long as this kind of steel can be produced, bulletproof vests can be made to replace the high-manganese steel seized from Yamamoto's special forces.

The old blacksmith stroked the blade and said with some emotion:
"This sandwiched steel isn't really steel, but a forging method. It's a skill most blacksmiths don't possess. According to my ancestors, this forging technique was invented during the Han Dynasty. Forging techniques like this have always been passed down orally, from father to son, and from son to grandson. Of course, this type of steel is difficult to forge, so I don't use this process when forging farm tools or ordinary knives..."

Perhaps because his son was already dead, or perhaps out of gratitude to Wang Gensheng for avenging his son, the old blacksmith told Wang Gensheng about the so-called sandwich steel forging process and method without hiding anything.

Following the old blacksmith's explanation, Wang Gensheng also understood what the clamped steel forging method is.

Sandwich steel is a method of combining the strengths of different steels, aiming to achieve a balance between the performance of two or more types of steel. When applied to knifemaking, this method typically uses lower-hardness, more-tough steel on the sides and higher-hardness steel in the center of the blade. This ensures a high-hardness edge while maintaining high toughness throughout the blade.

Many fine knives are forged using a clad steel process. The purpose is obvious: to combine the toughness of iron with the hardness of steel, while eliminating the softness of iron and the brittleness of steel. This is the principle behind the saying "the best steel should be used on the blade." These knives remain incredibly sharp and resist breaking, and are also easier to sharpen.

In order to increase the hardness of the blade edge, ordinary samurai swords usually add a covering and burning blade process. By covering and burning the blade, the hardness and toughness of the blade are increased.

After covering the blade with soil and burning it, a natural burning pattern will form on the blade, which is very beautiful. However, the knife with sandwich steel does not have a burning pattern because it is a composite steel material, made of soft steel wrapped around hard steel. After grinding, the sandwich steel pattern will appear on the blade, also known as the sandwich steel line, which is looming and looks like a line.

As the old blacksmith explained, Wang Gensheng also discovered that there was a faint steel wire a little further back on the blade of this royal samurai sword that could block bullets, proving that what the old blacksmith said was true.

Of course, after the old blacksmith's explanation, Wang Gensheng seemed to understand why the steel with sandwich material is more bulletproof than ordinary steel.

Although Wang Gensheng's cultural knowledge level was not high before he traveled through time, and he was not a materials expert, he knew that the so-called steel was actually an alloy of carbon and iron.

The higher the carbon content, the harder the material, while the lower the carbon content, the lower the hardness and the greater the flexibility. Softer iron is more susceptible to puncture, while harder iron, while less susceptible to puncture, cannot withstand impact and will shatter under the impact of a high-speed bullet.

So when sandwich steel appeared, the hard high-carbon steel was sandwiched between the soft steel. With the protection of the flexible soft steel, there was no need to worry about the high-carbon steel being easily damaged.

Since the flexible low-carbon steel has a high-carbon steel skeleton as its support, there is no need to worry about it being easily penetrated by high-speed bullets.

"Master, can you still make this kind of clamped steel?"

The old blacksmith looked at the question raised by the young leader and couldn't help but asked in confusion:

"I could still fight when I was young, but now that I'm old, I can't handle this kind of sandwiched steel anymore. Of course, if you want to learn, I can teach you this secret weapon! But now it's the world of firearms. No matter how good your sword is, you can't expect the Japs to always fight you with bayonets!"

"Of course it's not for making swords. This steel is good for making knives, but it's even better for making bulletproof plates!"

Wang Gensheng told the old blacksmith the real purpose of making the steel clamps. Of course, since the old blacksmith was not physically strong enough, Wang Gensheng naturally became an apprentice and followed the old blacksmith to swing the hammer.

The reason why Wang Gensheng is so obsessed with making bulletproof inserts is mainly because this bulletproof vest is really very useful in actual combat.

Apart from anything else, the high-strength bulletproof plate on Wang Gensheng's body, which came from the Yamamoto Special Forces, has saved Wang Gensheng no less than ten times.

The more than ten bullet holes on it also illustrate the importance of bulletproof vests. Moreover, as a hardcore player of Dark Zone Conflict, the importance he attaches to bulletproof equipment is unparalleled.

In Wang Gensheng's view, both the Japanese and the Eighth Route Army are players without armor, so once Wang Gensheng gets a level 6 helmet and a level 6 bulletproof vest, he can just kill them indiscriminately.

Of course, Wang Gensheng also knew that the weight of a level 6 helmet could easily reach five kilograms, and the weight of a level 6 armor could reach fifteen kilograms. The sum of the two was equivalent to asking the soldiers to carry a 20-liter bucket of water to charge.

However, Wang Gensheng did not think it was too much at all, because his men were cavalrymen. If they usually carried 20 kilograms of bulletproof equipment, plus 10 kilograms of light machine guns and some ammunition, the weight a soldier would carry could easily exceed 70 or 80 kilograms.

If you were to run for more than ten miles or even dozens of miles to attack the enemy wearing such a heavy thing, you would be exhausted to death, let alone attacking.

But Wang Gensheng is a cavalryman now! So he only needs to let the soldiers complete the last kilometer of the assault, and the rest of the journey will be carried out by war horses, so let alone 70 or 80 kilograms, even a hundred kilograms will not be a problem.

After all, if an adult man can't even carry a hundred pounds, then there's no point in fighting a war; he can just surrender.
