Looking at the powder steel thrown out by Zhou Yu, Qi Jinxuan hesitated, "Xiao Yu, it's not good to experiment with powder steel, why don't you find a small wire or something like that to try first." ”

How high is the hardness of powder steel, people who play knives know that some craftsmen who make knives use cutting tools that are made of powder alloy steel, and the hardness is high enough to cut high-hardness alloys.

It's just that the cutting of these craftsmen is not directly with a knife and cutting vegetables, but with a machine to rotate and cut at high speed, like cutting vegetables, I don't know if the knife is bad, human hands must be painful.

Even with this kind of high-speed rotating cutting knife, it is impossible to cut powder steel like cutting mud, and can only be cut slowly, so he is really worried.

Zhou Yu suddenly became happy, "Poof, wire, Brother Qi, you look down on my blacksmith master's skills, just follow the middle with a knife." ”

The kitchen knife he had just made at the beginning, cutting the bones of the spirit beast was as easy as cutting the mud, and he didn't feel the slightest obstruction, no matter how hard this powder steel was, it was just like the bones of the spirit beast.

Looking at Zhou Yu's confident appearance, Qi Jinxuan couldn't help but look at the knife with golden stars in his hand, could it really be able to sharpen iron like clay, he looked up at Xiaobao who was playing with the tablet not far away, shook his head and smiled, in this year in Taoyuan, even a dog can become a fine, and a knife that sharpens iron like clay is estimated to be very possible.

He took the small piece of powder steel on the table in front of him, held the knife in his hand, and cut it with a little force first, because he still had some doubts in his heart, if this knife could not sharpen iron like clay, it would still be able to protect the blade, and if he cut it hard, it might curl the blade.

Even if he can't sharpen iron like clay, in his opinion, the knife made by Zhou Yu is already a boutique among the best.

However, the knife in his hand stopped on the powder steel, and the situation of being blocked did not appear, and the knife in his hand actually cut directly into the powder steel, which was very smooth, and only felt a little weak obstruction.

There was a look of surprise on his face, and he involuntarily increased his strength, and the knife directly disappeared, splitting the powder steel in two.

Looking at the two halves of the powder steel on the table, the smooth and smooth incision, Qi Jinxuan's eyes widened, is this really the powder steel he just cut, it feels like he is cutting mud, no, even a little smoother than mud.

The problem is not mud, this is powder steel, the high-hardness steel alloy of various knife machinery is easily cut under the knife in his hand, he is really unbelievable, even powder steel is easily cut, it is estimated that the hand touches the blade, and the finger can be cut off.

"Brother Qi, it seems that you still don't believe it, come, cut another piece to practice your hands. Zhou Yu smiled and threw out another piece of powder steel that was bigger than just now.

This time, Qi Jinxuan first picked up the powder steel and observed it carefully, then pinched it with his hand to make sure it was complete, and then he picked up the knife and cut it again, sure enough, it was still the same feeling, the same taste, silky smooth.

His whole person was shocked, the legendary knife that sharpened iron like clay was really made by Zhou Yu, "Xiao, Xiaoyu, you, how did you make this knife, powder steel is really mud in front of this knife, it's like a dream." ”

"Poof, you're really dreaming, give me back the knife, and I'll send you out of your dream. Zhou Yu jokingly said, for the Xianxia world, the sword that sharpens iron like clay is simply not worth mentioning, and the power of some spiritual weapons can smash a mountain.

"This knife is in my hand, you still want to go back, impossible. Qi Jinxuan touched the knife and said lovingly, but he only dared to touch the blade, and he didn't dare to touch the blade.

The overall structure of this knife is very tight, and the golden stars on it seem to have turned the knife into a galaxy, and the entire knife is full of a heroic aura, which makes people feel calm.

"Why, now I believe it, I still questioned Master Ben's technique before. Zhou Yu snorted coldly and said.

"Master Zhou, I admire your skills for the five-body casting, how did you make it, there seems to be a heroic righteousness on it. Qi Jinxuan asked again, he was very, very curious.

The level of ancient smelting technology, although not as good as modern times, has many famous swords cast, blowing hair and breaking hair is no longer a dream, and sharpening iron like clay has always been in the legend, how long has it been since Zhou Yu asked him to buy powder steel, even if he learns it now, he can't learn it.

"This is the exclusive secret of this master, and it will not be passed on, this knife will charge you a million friendship price, not too much. Old man Zhou Yu smiled and stretched out a finger to open the price.

"One million is not too much, but, Master Zhou, you said that you would give me two knives, and the master has to talk about it. Qi Jinxuan said leisurely, this knife that sharpens iron like clay, if it is placed in the circle of the rich, let alone a million, tens of millions of people will buy it.

Not to mention anything else, the effect of pretending to be forced at the party is first-class, others use knives to cut steaks, let's use knives to cut powder steel to play.

"Hey, it's a loss, it's a loss, this business is a loss, come, you pick one more of these four knives. Zhou Yu shook his head and sighed, and took out the other four knives he had prepared, two of which were switchblades and were packed in small leather bags, and the other two were still fighting knives.

"There are four more, Xiao Yu, such a knife that sharpens iron like clay, you can still mass-produce, if it is put on the black market of knife collection, a knife is tens of millions, and there are local tyrants rushing to buy it. Looking at the four knives on the table, Qi Jinxuan glared and said in disbelief.

"I also have nothing to do with this knife, it is impossible to make it in large quantities, as for selling it to local tyrants, it is impossible, I will only give it to friends. Zhou Yufeng smiled lightly, not to mention tens of millions, even if it was 100 million, he would not sell it.

In the eyes of immortal cultivators, no matter how rich people are in the world, they will not care in the slightest.

"Poof, the master is really the master, he has nothing to do and play, and he reveals a bullish spirit when he speaks. Qi Jinxuan laughed, gave a thumbs up, then looked at the four knives on the table, and said with some eagerness in his eyes: "Then I can pick it." ”

In his opinion, two knives were enough, and it was useless to ask for one more, so he set his sights on two small bags, which had no scabbards and should be knives of different kinds.

He gently pinched the corner of the small bag, and gently poured out the knives in the two bags, and sure enough, it was two switchblades.

The handle of one knife is covered with green bamboo and wood, and the other handle is leather, and both knives seem to be spring-shaped jump knives with buttons on the side.
