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

"Damascus pattern, before pickling, you have to do the whole knife well,

So we have to sharpen the knife well, and we have to sharpen the blade.

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

After the pickling is done, just wipe the knife out. ”

Guo Shugui and Liu Xiaodong listened carefully, what Li Zhenhua said was popular science knowledge.

Guo Shugui suddenly realized at this moment that the pickling was to be carried out at the end, and he thought that the pickling process was carried out in the middle.

"So what are we waiting for? Huazi, hurry up and give the knife a blade,

After opening the front, and then polishing, we quickly pickled, I can't wait to see the finished product. ”

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

Armed with a knife, he walked towards the belt grinder.

In fact, for the cutting edge of the table knife, Li Zhenhua did not think of a good way,

The blade of a general table knife is actually jagged, and the shape of the blade makes it easier to cut meat with a knife.

But for Li Zhenhua, he has no way to grind these sawtooth out.

Since the sawtooth can't be sharpened, and the effect still has to be achieved, the knife can only be sharpened as much as possible.

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

However, if the hardness is high, the grinding belt for sharpening the knife may be consumed quickly, which is the only disadvantage.

Come to the abrasive belt machine. Li Zhenhua turned on the machine, and the abrasive belt rotated.

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

After the abrasive belt and the table knife come into contact, sparks are flying, and these flying sparks are produced by the high temperature of the grinding iron filings and grinding stones.

The table knife was quickly taken down by Li Zhenhua, and he held it in his hand and watched the blade.

"Fat man, come here."

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

"What? What's the matter? ”

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

"Fatty, quick, pull your trouser leg up,

Come, with your feet, step on this bench"

Li Zhenhua continued to instruct Liu Xiaodong, but he remained puzzled, exposed his legs, and stepped on the bench.

Originally, it was hidden in the pants, and 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 leg 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 covered his hairy legs with his hands.

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

"!"

For Li Zhenhua's answer, Liu Xiaodong felt bad.

"Tell me what you're going to do, or I'll go home, and my mom said to introduce me to a blind date!"

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

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

Auntie also found you a blind date, did you ever think of Wang Mei when you said this? ”

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

"Damn, don't hurt me! Don't you come here......"

After Liu Xiaodong finished speaking, he closed his eyes and looked like he was letting things go.

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

"Huazi, uh, there's a video, it's been recorded."

"Great" "Let me die"

The reactions of the two people were in stark contrast, especially Liu Xiaodong's fear.

Liu Xiaodong, who was grabbed by Li Zhenhua, stretched his legs and didn't dare to move again.

Li Zhenhua took the knife and moved his hand on the fat thigh.

I saw the blade pass by, and the leg hair fell to the ground.

It was originally a very dense hairy leg, but a furrow appeared in the middle.

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

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

"Brother, I didn't expect your hairy legs to be so white, how about my knife, it can be called a hair-picking and broken hair!"

"My woolen pants, I didn't expect you to leave me like this, don't worry, I'll miss you."

Liu Xiaodong faced his changed legs, there was no joy or sadness on his face, and he was still playing treasure on the side.

Guo Shugui was also very happy to see the effect achieved by the table knife,

I didn't expect that one of my own proposals would actually get such a forged table knife.

This directly improves the quality of one's own commercial housing from a small detail.

"Oh, this knife is really fast, hurry up, let me see, fat man, you stand there, let me have a knife."

Guo Shugui saw that the knife had achieved this effect, and hurriedly said on the side.

Liu Xiaodong immediately ran away and asked Li Zhenhua to use a knife, because he knew that Li Zhenhua had a number in his hands, but he didn't 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, the color of the blade becomes bright under the sandpaper polishing of these meshes.

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

This first sample Li Zhenhua was sharpened by hand, and when the large batch was later, he began to make a simple device to sharpen the knife.

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

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

The two of them immediately came together.

"Can Huazi's knife take the next step? It's so bright, it's all out of the mirror effect. ”

Guo Shugui looked at the knife on the side and sighed.

"I grinded to 2000 mesh, and when it came to mass production,

As long as it reaches 600 mesh, it is enough, and this one is used as an experiment, so it is better sharpened.

You two wait, I'll go get hydrochloric acid, you can pickle it in a while, and when the pickling is finished, this knife will be even more beautiful. ”

Saying that, Li Zhenhua walked into the warehouse, and came out after a while, still holding a few bottles of mineral water in his hands, and the bottles still contained colorless transparent solutions.

Come to the plastic keg prepared in advance, put a few bottles of solution in your hand,

With the aid of the Analytical Eye, it was poured into the bucket in proportion.

Guo Shugui and Liu Xiaodong watched from the side, and the two discussed from time to time, like two stinky chess baskets playing chess, and they also praised each other in the middle.

After mixing the solution, Li Zhenhua hung the knife with iron wire and put it into the solution.

Li Zhenhua put 24V electricity on the knife again, and the next thing is to wait.

The stainless steel knife reacts in the solution, and the solution also changes from colorless and transparent to rust-colored and green through the silk.

Twenty minutes passed, and Li Zhenhua fished out the dinner 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, and they saw that the knife showed a beautiful pattern.
