Li Zhenhua glanced at Liu Xiaodong and pointed at him.

" Damascene pattern. The knife must be made whole before it is washed with acid,

So we still have to sharpen the knife, and sharpen the blade,

Only when these two processes are completed can acid washing be carried out,

After the acid wash is done, it's just a simple matter of wiping the knife."

Guo Shugui and Liu Xiaodong listened attentively. What Li Zhenhua said could be considered common knowledge.

Guo Shugui suddenly realized that the acid wash had to be done at the end. He had thought that the process would be carried out in the middle.

"Then what are we waiting for? Hua Zi, quickly sharpen the blade.

After the cutting and polishing, let's quickly do the acid washing. I can't wait to read it."

Listening to Guo Shugui's urging and Liu Xiaodong's agreement, Li Zhenhua took the knife from the fatty.

He walked toward the sandbelt machine with the knife.

Actually, Li Zhenhua did not think of a good way to use the knife.

The usual knife blade was actually serrated. The shape of the blade made it easier to cut meat.

But for Li Zhenhua, he had no way of grinding out these saw teeth.

Since the sawtooth could not be sharpened, and the effect had to be achieved, he could only sharpen the knife as sharp as possible.

Fortunately, after these two types of stainless steel knives were forged, they were very hard after being quenched. This also had a greater positive effect on whether the blade could be sharpened.

However, with higher hardness, the sand belt of the sharpening knife might be used up quickly. That was the only bad thing.

Reaching the sandbelt machine. Li switched it on. The sandbelt turned.

The knife was fixed to the clamp that had just been adjusted by Li Zhenhua. Then, the knife began to grind on the sand belt.

Sparks flew as the belt of sand came into contact with the knife. The sparks were produced by the high temperature of the ground iron and grinding stone.

Li Zhenhua quickly took down the knife and held it in his hand to look at the blade.

"Fatty, come here."

Hearing Li Zhenhua calling him, Liu Xiaodong hurried over to Li Zhenhua's side.

"What? What is it?"

Li Zhenhua did not answer Liu Xiaodong's question.

"Fatty, quick, pull your pants up,

Come, use your feet and step on this stool."

Li Zhenhua continued to instruct Liu Xiaodong. He maintained his doubts and exposed his legs to step on the bench.

Guo Shugui couldn't see it, but at this moment, he saw that this fatty actually had such natural 'furry pants'.

When Li Zhenhua saw the fur pants, he immediately squatted in front of Liu Xiaodong with a knife.

Crouching in front of him with a knife, Li Zhenhua looked at the hairy legs and even smiled.

This frightened Liu Xiaodong so much that he covered his hairy leg with his hand.

"Wah, what do you want?"

"Fuck!"

Liu Xiaodong felt uncomfortable with Li Zhenhua's reply.

"Tell me what we're going to do, or I'll go home. My mother even said she'd introduce me to a blind date!"

Liu Xiaodong was so frightened that he quickly retracted his leg and took a few steps back.

"You idiot. Fatty, look at how scared you are. You can't even lie. I should have recorded it for you and left some evidence.

Auntie even found you a blind date. Did you think about Wang Mei when you said that?"

Liu Xiaodong, who was still retreating, immediately stopped when he heard Li Zhenhua's words.

"Holy shit, don't hurt me! Don't come over…"

After Liu Xiaodong finished speaking, he closed his eyes and looked like he was willing to do whatever he wanted.

At that moment, a weak voice came from the side. It was Guo Shugui.

"Hua Zi, uh, there's a video. It's been recording."

"Great." "Let me die."

Their reactions formed a sharp contrast, especially Liu Xiaodong's.

Liu Xiaodong, who had been caught by Li Zhenhua, did not dare to move again.

Only then did Li Zhenhua take the knife and start working on the fat thigh.

The hair from his leg fell to the ground where the blade passed.

A gully appeared in the middle of the thick hairy leg.

The gully was made by Li Zhenhua with a knife.

Li Zhenhua looked at his masterpiece and asked Liu Xiaodong proudly.

"Brother, I didn't expect your hairy legs to be so fair without the hair. How about it? My saber can be said to be able to shave hair off very well!"

"My fur pants. I can't believe you left me like that. Don't worry, I'll miss you."

Liu Xiaodong's legs had already changed. There was no joy or sadness on his face. He was still playing around.

Guo Shugui was also very happy to see the effect of the knife.

He did not expect to get such a forging knife for one of his proposals.

This small detail directly raised the quality of his commodity.

"Ouch. That's a fast knife. Quick, quick, quick. Let me see it. Fatty, stand there and let me make a cut."

Guo Shugui saw that the knife had achieved this effect and quickly said.

Liu Xiaodong immediately ran away and let Li Zhenhua use the knife because he knew that Li Zhenhua knew what he was doing, but he did not trust Guo Shugui.

Li Zhenhua looked at the two people who were fighting and walked towards the first floor with the knife in his hand.

400, 600, 800, 1500, 2000. Under the sandpaper of these orders, the color of the knife brightened.

He could still vaguely see the pattern of folding and forging on the blade.

Li Zhenhua ground the first sample by hand. When he made a large batch later, he started to build a simple device to sharpen the knife.

The knife had been sharpened. The next step was the process of acid washing.

Li Zhenhua came to the courtyard. Liu Xiaodong and Guo Shugui had stopped playing. When they saw him walk out, the knife in their hands had changed.

The two immediately moved closer.

"Hua Zi, are you going for the next step? It's so polished that it has a mirror effect."

Guo Shugui looked at the knife and sighed.

"I've sharpened to 2,000 grit. When it's time to mass-produce,

sharpening to 600 grit would be enough. This one was used as an experiment, so I made it with a higher quality.

Wait here, you two. I'll get the hydrochloric acid. It'll be ready for acid washing in a moment. By the time it's done, this knife will be even more beautiful."

With that, Li Zhenhua walked into the storeroom and came out in a moment. He was holding a few mineral water bottles that were still filled with a colorless transparent solution.

to the little plastic bucket that had been prepared in advance, and put the bottles of solution in his hand,

With the aid of the Eye of Analysis, he poured it into the bucket in proportion.

Guo Shugui and Liu Xiaodong watched from the side. The two of them even discussed it from time to time, like two smelly chess baskets playing chess.

After mixing the solution, Li Zhenhua hung the knife on a wire and placed it in the solution.

Li Zhenhua turned on the 24v electricity again. All that was left was to wait.

The stainless steel knife reacted in the solution. The solution also changed from its original colorless transparency to the color of rust with traces of green.

Twenty minutes passed. Li Zhenhua fished the knife out of the bucket.

A simple wash with water, a wipe with a rag.

The knife that had already been made was placed in front of the two of them. Beautiful patterns appeared on the knife.
