Looking at the two pieces of iron, Liya almost subconsciously stretched out her hand, she really wanted to touch it, because she could not feel that they were extremely hot things, but... it seemed to be. A very soft and flexible thing.
Snap, one sound.
Lu Yu's hand outstretched was hit by Lu Yu.
Liya was surprised, and hurriedly took her hand back.
Lu Yu asked inexplicably, "What did you... What were you doing just now? Is it possible that you want to touch them?"
Liya smiled bitterly and said, "It's just... it doesn't feel as hot anymore..."
Lu Yu couldn't help rolling his eyes and said: "On the contrary, the temperature that they can release now is higher than that of molten iron! This is the truth that things must be reversed. Such a shape and such a state can allow it to Most of the heat is'contained' in it. If you touch it, you can only cut off your fingers."
"what!"
Liya quickly took a few steps back again.
Lu Yu smiled lightly, and then resumed his work.
The next thing is actually very simple, at least it looks very simple.
The big piece of iron, a few hammers down, made a depression appear in the middle of it, and a few more hammers, the depression becomes bigger and bigger, and extremely even.
Lu Yu put the small piece of iron directly in the depression in the middle, then turned it over and smashed it from the side... The two pieces of iron were completely connected together.
It's like a steamed bun, the dough is separated from it, and a piece of plump meat is sandwiched.
Then there is beating.
The small hammer flew up and down, and after a while, the shape of a kitchen knife appeared.
After three times of returning to the furnace, and then forging, the shape of the kitchen knife has been completely settled.
However, Lu Yu's little hammer still had no intention of stopping, knowing that the red light on it had disappeared and then turned into an ugly black, but Lu Yu still kept beating.
As he beat, the black gradually disappeared, and the blade of the kitchen knife became smoother and smoother. In the end...Although the color was still biased towards black, the surface was smooth enough to reflect human shadows clearly, even with a bronze mirror. I'm afraid it's not so smooth.
Liya looked dumbfounded, staring blankly at the thick color and mysterious luster that made people fascinated, she felt that the kitchen knife was beyond the level of beauty.
But Lu Yu's beating did not stop, as if a certain rhythm, a very crisp sound, which made people not impatient at all, as if listening to this sound, you could sleep.
In the end, Lu Yu's main hitting place stayed on the blade, flipping back and forth, hitting back and forth, almost smooth and perfect.
What is the sharpest knife in the world
Lu Yu in his previous life once thought that the blade cut by laser was definitely the sharpest in the world, because laser cutting technology has almost reached the molecular level, and that sharpness is no longer just as simple as'sharpness'.
There is even a conjecture that if there is an extremely good metal that can maintain its solidity at the single-molecule level, then if the laser cutting technology is used to sharpen the edge, the knife can be used to cut anything. At times, it is like cutting a piece of tofu, because it can directly separate the molecular level of things.
Even... If the speed is fast enough, the thing that has just been cut apart, and then put it back... It will be restored as it has never been destroyed.
Of course, this is just an illusion, but the cutting edge of laser cutting technology should indeed be the sharpest in the world.
However, Lu Yu’s assertion was immediately broken by an old man, an old man who can be called a master even in modern society. He used a small hammer and a piece of ordinary iron to beat it out. The sharp blade is really... sharper than the laser-treated knife.
This is knives.
Knife technique started in the Sui Dynasty, flourished in the Tang Dynasty, and destroyed in the Yuan Dynasty. During the period, a little bit of fur was spread in the southwest island country during the Tang Dynasty, and it barely spread to modern times.
Even so, the knife is still the forging method with the best elasticity and sharpness among all forging methods.
This is what Lu Yu is doing now.
After the last hammer strike, Lu Yu stopped, wiped the sweat from his forehead, then smiled lightly, and said, "Well, heat, strength, and mastery of this metal... Well, I finally didn't completely forget the handwork."
After finishing speaking, I randomly made a simple handle of the kitchen knife in my hand, fixed it with iron welding, and then handed it to Liya, saying: "Hey, this is for you. I used your kitchen knife before, so I will use this later. All right."
Liya was taken aback again, carefully took the kitchen knife over, and immediately saw her shadow clearly from the reflection of the knife, with a look of affection.
Lu Yu said, "Be careful, don't cut your hands."
Liya smiled and stroked the blade and said: "I have cooked for half my life, and I have been with this kitchen knife every day. How could I be cut... Huh?"
While talking, she found blood on the knife.
Take a closer look, it is her blood, because the blood is flowing out of the fingers.
However, she has not felt the pain until now!
Lu Yu rolled his eyes and said, "What am I talking about? Just to make you be more careful, and the result... Hey, Xiao Ruan, give her a bandage."
Xiao Ruan nodded, and walked over to take the kitchen knife and put it on the table, and then tied the wound on Liya's hand with a cloth strip. Because the incision was too sharp, the wound should heal easily.
Lu Yu said: "This knife is indeed a bit sharp, I don't know if it is suitable for you to use..."
After all this for a long time, Liya was still in a sluggish state, she still didn't want to understand, she didn't touch the edge at all, why... was she cut
However, the late pain still made her sober.
"This... Isn't this too sharp? It can't be so sharp..."
Lu Yu smiled bitterly: "Of course it is sharp..."
While talking, he took out an apple from the fruit plate on the table, just put it on the table like this, then took the kitchen knife, and cut it diagonally and straight from the top right to the bottom left...
The apple didn't move, but was cut in half. The upper half slipped smoothly from the apple, and then... Until then, the apple itself shook.
An apple is placed on the table, not to mention the use of cutting, as long as it is not held, I am afraid that it will shake with a breath, but just when it was cut, it still remained motionless...
Moreover, Lu Yu's movements were obviously lighter as if he was stroking, without the sensation of exerting force at all.
Liya stared at her with rounded eyes, but still did not speak.
Lu Yu curled his lips and looked at the candlestick on the table. The candlestick was made of copper and very strong. It was divided into three forks, like forks for carrying grass.
Lu Yu lightly waved the kitchen knife, but didn't hear the sound. A "fork" of the candlestick fell directly on the table. The port was flat and smooth. The most important thing was that the original golden color of the bronze was revealed, revealing the surrounding scenery. Reflected on it, it looks... actually very beautiful.
"This...Where is this still a kitchen knife? This is clearly a magic weapon!"
Liya finally spoke, and she yelled out directly.
Lu Yu spread his hand and said, "No, it's not a weapon. The weapon is more complicated than this. This is a kitchen knife, and it will also be your kitchen knife in the future. But if we sell it, we can't sell this kind of thing. It’s a lot of trouble, but it’s better to get some ordinary ones... By the way, I will use the cast iron fence at the door for the time being. I hope that our small shop can open tomorrow morning."
After speaking, he walked out. Before Liya could react, Xiao Ruan had already walked in carrying a fence more than one meter wide.
When the hand lifted the knife and fell, the fence turned into small iron pillars, and then they were thrown into the fire.
This time, Lu Yu moved extremely fast. Several iron pillars close to the fire were first burnt red, and then he took them out. After a few beats, it took a cup of tea, and a kitchen knife was enough. He figured out the shape, and then threw it into the basin next to it... With a bang, the prototype of the kitchen knife appeared.
Just as Lu Yu was beating, Xiao Ruan went out and made a circle, and when the quenching was completed, she had already returned with a millstone.
The grinding disc is not too big, it is only one foot wide in diameter, and it is a kind of hand grinding.
Perfectly round and hollow.
With an iron rod passing through the middle, Xiao Ruan stood up the grinding disc, and when he reached out his hand, the grinding disc spun wildly on the iron pillar, like a wheel.
Lu Yu put the kitchen knife that had just been quenched against the spinning grinding disc, and a burst of sparks fluttered. It took only a while, including polishing and sharpening, to be completed.
Bai Liang is white and bright. Although it looks rough, it is much better than Liya's chopper that was broken by Lu Yu.
