Start with a blacksmith shop.

"It's been filmed, it's been filmed. Don't worry, not a single shot will be missed. The organizing committee will see the whole process later."

Guo Shugui said to Li Zhenhua, who was walking ahead.

Li Zhenhua carried the soil back to the blacksmith's shop and put the dug-up raw soil together with the previous materials.

Liu Xiaodong put the two tools he was holding in the corner and then went to Li Zhenhua's side.

Li Zhenhua was holding a measuring tool and fiddling with the prepared raw materials.

"What are you planning to do? I don't understand at all."

This includes charcoal, coal, and the soil we dug up.

While weighing the various raw materials, Li Zhenhua answered Liu Xiaodong's questions.

"Hehe, you don't understand, do you? I'm preparing something for quenching."

This is called clay tempering. Do you know what clay tempering is?

This is a unique quenching method. The principle is actually very simple: only the blade edge is quenched, while other parts of the blade body are not quenched.

I'll explain as I go, so watch carefully!

Li Zhenhua said that his hands did not stop moving, but instead he took a measuring cup and put some iron powder into it.

Immediately, Li Zhenhua noticed the weight of the iron powder: 1000g.

Pour the iron powder from the measuring cup into a bowl, and use the measuring cup to measure other ingredients.

Soon after, iron powder, raw soil, borax, charcoal powder, and carbon powder were poured into the basin, all weighed according to the proportions given by the analytical eye.

Li Zhenhua held an iron rod and stirred the mixture in the basin, thoroughly blending the various ingredients together.

He took a gourd ladle and scooped a ladleful of water from the water vat next to him, then poured it into a basin.

The small iron rod came in handy once again, stirring the contents of the basin. As the various things in the basin were mixed with the water, they turned into a basin of mud.

"Fatty, look, this is the mud we'll smear on the knife later. We'll cover the whole knife with it and then put it in the stove to heat it."

After the mud-coated blade had been heated to a certain temperature, I put it directly into the water.

This allows the exposed blade to cool down rapidly, achieving the purpose of quenching.

As for the parts covered in mud, because the mud acted as a barrier, these parts were not quenched and retained their toughness.

As Li Zhenhua spoke, his hand movements remained completely unaffected.

Liu Xiaodong and Guo Shugui stood to the side, looking like they were being taught a lesson.

Li Zhenhua took a small spatula, scooped some mud from the basin, and then smeared it on the blade.

In no time, the blade was covered in mud, leaving the blade exposed.

Li Zhenhua then took out a special long ruler with a wavy shape from the side and began to scrape it near the blade.

On the blade, near the edge, a smooth wavy line appeared.

Li Zhenhua turned on the preheated electric heater and placed the knife blade, whose handle had been tied with wire, into the heater.

Once the temperature is set, all that's left is to wait for it to reach the specified quenching temperature.

More than ten minutes later, the mud that had been smeared on his body had already solidified on the blade under the high temperature.

The exposed blade was already glowing red-hot from the heat of the furnace.

Li Zhenhua opened the furnace door, took an iron hook, and hooked the wire on the knife handle.

The knife was taken out and exposed to the air. Looking at the temperature displayed in the eyes, it was just right for this quenching.

Without saying a word, Li Zhenhua went straight to the water tank filled with water.

Then he immersed the knife in the groundwater, and the water tank became foggy again.

When a knife comes into contact with water, the temperature of the exposed blade drops rapidly.

A short while later, Li Zhenhua looked into the water tank.

Li Zhenhua could see that the blade in the water tank had reached a hardness of 58.

Take the knife out of the sink, place it on the table, and use a small hammer to knock off the hardened brick-like coating on the blade.

Then the whole set was presented to the three of them.

Liu Xiaodong was also curious and somewhat puzzled by Li Zhenhua's method of sintering and tempering the blade with clay.

Upon seeing the knife, he reached out towards the hilt.

Just as Liu Xiaodong's hand was about to touch the knife.

"Be careful with your skin, or you'll burn your hands! Don't blame me if you don't!"

Upon hearing Li Zhenhua's words, Liu Xiaodong immediately withdrew his outstretched hand.

When they came back, they saw Liu Xiaodong still muttering to himself:

"It's already been quenched, and the knife doesn't even look that hot! Why can't I try it out first?"

The knife was left to cool on the cutting board. Only when the temperature of the knife dropped to a point where it was safe to touch did Li Zhenhua speak to Liu Xiaodong.

"Go up and get it. Let you experience it first. Remember to bring it back to me later. I'll go prepare the things I need later."

As he spoke, Li Zhenhua walked to the corner of the wall and moved the long bench to the center of the yard.

He went back to the first-floor room, took a stack of sandpaper, and sat down on a long bench.

Liu Xiaodong was also very perceptive; he handed the knife in his hand to Li Zhenhua.

"It feels better to use than the controller; it's too uncomfortable to hold."

Li Zhenhua looked at Liu Xiaodong, the fat man, with an expression as if he were looking at a fool.

"Damn it, how can it be comfortable? Didn't you even check if the hilt was attached?"

After finishing his sentence, Li Zhenhua didn't dawdle any longer. He took the knife and proceeded with the same routine as before: sharpening, shaving, and polishing.

After Li Zhenhua had been busy for another two hours, a kukri without a handle was presented to the three of them.

Now, once the handle is finished, this knife will be a complete product.

It's more than capable of chopping melons and vegetables; it won't fail you even if you take this knife to the battlefield.

A piece of steel made from pig iron, which is then folded and forged to create patterned steel (refined steel).

Finally, the Gurkha knife, forged from patterned steel, was placed by Li Zhenhua on the cabinet on the first floor.

There was a piece of velvet cloth placed under the blade, for fear of scratching the freshly polished blade.

"Hua Zi, is the knife done now? Should we call the delivery guy and have him come pick it up?"

Guo Shugui picked up a camera from the side, and the lens was replaced with a damaged macro lens.

He photographed every detail of the body, down to the smallest scratch on the knife.

All of these can be captured by the camera lens.

"Next, we need to send the package. We can't let the delivery guy come."

We went straight to the courier station. When we got there, I had to watch them pack our knife!

Otherwise, I wouldn't trust the delivery guy to pack the knife according to my instructions.

The three men grabbed knives, and Liu Xiaodong drove towards the courier station.
