Start with a blacksmith shop

After hearing this, Li Zhenhua glanced at Liu Xiaodong and tapped him with his hand.

"With Damascus pattern, the entire knife must be done before pickling.

So we still have to sharpen the knife and sharpen the edge.

Only after these two processes are completed can pickling be carried out.

After the pickling is completed, just wipe the knife out. "

Guo Shugui and Liu Xiaodong listened carefully. What Li Zhenhua said was considered popular science knowledge.

Guo Shugui suddenly realized at this moment that the pickling process was done at the end. He had thought that the pickling process was done in the middle.

"Then what are we waiting for? Hua Zi, hurry up and sharpen the knife.

After cutting and polishing, we quickly started pickling. I couldn't wait to see the finished product. "

Listening to Guo Shugui's urging from the side and Liu Xiaodong's echo, Li Zhenhua took the knife from the fat man's hand.

He took the knife and walked towards the belt sander.

In fact, Li Zhenhua didn't think of a good way to sharpen a table knife.

The blade of a general table knife is actually serrated. This blade shape makes it easier to cut meat with the knife.

But for Li Zhenhua, he had no way to grind out these saw teeth.

Since the saw teeth cannot be sharpened and the effect still needs to be achieved, the only option is to sharpen the knife as sharply as possible.

Fortunately, after the knife is made from these two kinds of stainless steel, it has a high hardness after quenching, which also has a great positive impact on whether the blade can be sharpened.

However, the higher the hardness, the sharpening belt may be consumed faster, which is the only disadvantage.

Come to the belt sander. Li Zhenhua turned on the machine and the sanding belt rotated.

The table knife was fixed by Li Zhenhua on the jig that had just adjusted the angle, and then the table knife began to be sharpened on the abrasive belt.

After the abrasive belt comes into contact with the table knife, sparks will fly. These flying sparks are caused by the high temperature of the ground iron filings and the grindstone.

The table knife was quickly taken down by Li Zhenhua, holding it in his hand and looking at the blade.

"Fat man, come here."

Hearing Li Zhenhua calling him, Liu Xiaodong quickly came over and came to Li Zhenhua's side.

"What? What's the matter?"

Faced with Liu Xiaodong's question, Li Zhenhua did not answer his question.

"Fat man, hurry up, pull up your trouser legs.

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

Li Zhenhua continued to give instructions to Liu Xiaodong. He remained doubtful, exposed his legs and stepped on the bench.

Originally hidden in his pants, Guo Shugui couldn't see it, but at this moment, he saw that this fat man actually had such a pair of natural wool pants.

When Li Zhenhua saw the woolen pants, he immediately squatted in front of Liu Xiaodong's legs with a knife.

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

This frightened Liu Xiaodong and he covered his hairy legs with his hands.

"Brother Hua, what do you want to do?"

"Dry!"

Liu Xiaodong felt bad about Li Zhenhua's answer.

"Explain clearly what you want to do, otherwise I will go home. My mother even said that she would introduce me to a blind date!"

Liu Xiaodong was frightened and quickly retracted his legs and took several steps back.

"You idiot, fat man, you are so scared that you can't even lie. I should really record it for you and leave a piece of evidence.

Your aunt is looking for a blind date for you. Did you ever think about Wang Mei when you said this? "

Liu Xiaodong, who was still retreating at first, immediately stopped after hearing Li Zhenhua's words.

"Fuck, don't hurt me! Don't come over..."

After Liu Xiaodong finished speaking, he closed his eyes and looked like he was letting what was done to him.

At this moment, a weak voice came from the side. It turned out to be Guo Shugui.

"Hua Zi, uh, there is a video, and it has been recorded."

"Great" "Let me die"

The reactions of the two people were in sharp contrast, especially Liu Xiaodong who was particularly scared.

Liu Xiaodong, who was caught by Li Zhenhua, stretched out his legs and did not dare to move anymore.

Li Zhenhua then took the knife and moved his hand on Fatty's thigh.

Wherever the blade passed, the leg hair fell all over the place.

There was a ravine in the middle of my originally very thick hairy legs.

The ravine was apparently scraped out by Li Zhenhua with a knife.

Li Zhenhua looked at his masterpiece and asked Liu Xiaodong with a proud look on his face.

"Brother, I didn't expect your hairy legs to be so white. How about my knife? It can be called a hair blower!"

"My wool pants, I didn't expect you to leave me like this. Don't worry, I will miss you."

Liu Xiaodong looked at the changed legs, and there was no joy or sorrow on his face. He was still playing tricks on the side.

Guo Shugui was also very happy when he saw the effect achieved by the knife.

I didn't expect that one of my suggestions would lead to such a forged table knife.

This directly improves the quality of our commercial housing in small details.

"Oh, this knife is so fast. Come on, come on, let me see. Fatty, stand there and let me strike."

Guo Shugui saw the knife achieving this effect and hurriedly said to the side.

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

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

400, 600, 800, 1500, 2000, when the table knife is polished with these grit sandpapers, the color of the blade becomes brighter.

You can still vaguely see the folded and forged pattern on the blade.

Li Zhenhua polished the first sample by hand. When the batch was later made, he began to make a simple device to sharpen the knife.

The knife has been sharpened, and the next step is the pickling process.

When Li Zhenhua came to the yard, Liu Xiaodong and Guo Shugui had stopped fighting. When they saw him coming out, the knife in his hand had changed.

The two of them immediately came together.

"Is Huazi's knife ready for the next step? It's so polished that it has a mirror effect."

Guo Shugui looked at the knife and sighed.

"I polished it to 2,000 mesh, and when it comes to mass production,

As long as it is 600 mesh, it is enough. This one was used as an experiment, so it was better polished.

You two wait, I'll get the hydrochloric acid, and I'll pickle it soon. When the pickling is done, the knife will be even more beautiful. "

As he spoke, Li Zhenhua walked into the warehouse and came out after a while, holding several mineral water bottles in his hands, which also contained colorless and transparent solution.

Come to the plastic buckets prepared in advance and hold the bottles of solution in your hands.

With the help of the analytical eye, it was poured into the bucket in proportion.

Guo Shugui and Liu Xiaodong were watching from the side, and they would discuss it from time to time, just like two bad chess players playing chess, complimenting each other in the middle.

After mixing the solution, Li Zhenhua hung the knife on a wire and put it into the solution.

Li Zhenhua connected the 24V power to the knife again, and then waited.

The stainless steel knife reacted in the solution, and the solution changed from colorless and transparent to rust-colored with a hint of green.

Twenty minutes passed, and Li Zhenhua fished out the knife from the bucket.

Simply rinse with water and wipe with a rag.

The table knife that had been made was placed in front of the two of them, and there were beautiful patterns on the knife.
