The ironware I made shines

Chapter 105 Forging Communication

The samurai sword is different from Chinese swords. Its major feature is its large bending range. Direct bending with a forged blade will destroy the strength of the blade. Therefore, to solve this problem, Yamamoto Yuji adopted a combination of multiple steel materials. characteristic way.

Simply put, the folded steel is just the middle part, the back of the knife is soft steel, which makes it possible to bend, the blade is hard steel, which increases the sharpness, and different steel materials are fused together forging and forming, and this is the combination of rigidity and softness of the samurai sword One of the secrets!

"The inlaid forging method is too difficult to master, and it is easy to waste all previous efforts." Ge Xiaohua, as an expert, knows very well that the fusion of different steel materials is more difficult than a single forging.

The prototype of the samurai sword blade came out, and Yamamoto Yuji asked several disciples to step back, and he held the blade very sacredly, preventing it from being placed on a special wooden stand, and was sitting and applying clay and charcoal powder to the blade.

"John, what is Master Yamamoto doing?"

"At the critical point of quenching, Mr. Yamamoto used the secret quenching clay."

Ge Xiaohua looked at it, and it was indeed going to be quenched. After applying the secret mixture, Yamamoto Yuji asked his disciples to close the doors and windows, and drew the curtains. The already dark forging studio was suddenly dark, and the camera turned on night vision function, while others remain silent.

The reason why Yuji Yamamoto closed the doors and windows, and even drew the curtains, was simply to observe the color of the flame. When quenching, temperature control is extremely important. It all depends on the blacksmith's eyesight. Ge Xiaohua also has his own experience when quenching, but It doesn't all depend on looking, but the body's subtle feeling of temperature is also the reason for the high success rate of quenching.

Putting the knife embryo into the carbon fire, Yamamoto Yuji observed the color of the flame, from red to blue, and the temperature reached about 800 degrees. The red-burning knife embryo was pulled out by Yamamoto Yuji. Master Yamamoto drew out the knife in one go Immediately put the embryo into the pool for quenching. As the blade cools down rapidly, the pressure on the steel with different strengths is different. The back of the blade bends first, which is also the symbol of the samurai sword!
After successful quenching, the back of the knife has a bend visible to the naked eye, and the forging of the blade body is considered to be initially completed, followed by grinding, polishing, and the production of the handle and scabbard.

"Master Yamamoto sharpens his knives with a whetstone?"

"Yes, this kind of special polishing whetstone is very valuable. The value of each stone of different thickness is different. It is said that the top-sized whetstone costs thousands of dollars." John said in a low voice, and then the whole The studio only hears the sound of sharpening knives, and Yamamoto roughly grinds and polishes the prototype of the samurai sword he created.

"Okay, the next step of polishing and polishing will be handed over to my eldest brother, His Excellency Yamamoto Yudai. His polishing and polishing skills are second to none."

It is said that polishing and polishing alone takes several months. The polishing and polishing of RB katana swords are all done by hand, so the efficiency will be much lower, but because this is an extremely patient skill, the requirements for craftsmen are higher. , Yuda Yamamoto is comparable to a professional polishing master in terms of re-polishing, so it is normal to hand it over to Yuda Yamamoto. Then for a few days, repeat the same sharpening action.

After watching the previous few days, Ge Xiaohua understood why the RB Samurai Sword is so famous. It is one thing to follow the ancient method. The craftsman's intention, patience, and hard work are worth learning from the Chinese people.

Grinding a knife for a few days is already the limit for Ge Xiaohua, and it is said that Yamamoto Yuda spent half a year grinding a samurai sword...

Yamamoto Yudai looks very honest, he basically doesn't speak much, when sharpening the knife, his hands are very steady, he can keep the same movement for a long time, and his body is much stronger than his brother.

Ge Xiaohua has been in RB for a long time, and has basically seen the whole process of katana swords. This kind of handmade katana sword is generally worth about 5000 US dollars to 2.5 US dollars, and this one belongs to the boutique level, at least 10. More than [-] US dollars, produced by the Yamamoto family, this is a priceless work of art.

"Ge Xiaohua? Hello, please give me your advice." Ge Xiaohua rested in the hotel. After watching the process of sharpening the knife for a few days, he was a little bored, so he explained the situation to John and planned to leave Kyoto to return to China. The harvest this time is still huge.

I was still packing my luggage when I heard someone knock on the door. A 1-meter-long thin RB man stood at the door and spoke in broken Chinese.

"Master Yuji Yamamoto? How do you know my name?" Ge Xiaohua thought for a while, and it was probably John who "leaked the secret", but it was unlikely. Leaking the secret would not do John any good. After all, he was Yuji Yamamoto's apprentice, so he said Afterwards, you may be punished.

"Don't worry, it's not what John said, but I know it myself. Think about it, I also studied in the United States, so I will also watch some programs in the United States, not to mention that I will be present in this season's championship competition. "

"what?"

Yuji Yamamoto did not expect that he was also a well-trained guest, and Ge Xiaohua felt a little embarrassed. Didn't he come here this time with the intention of investigating the enemy's situation?This time, Yamamoto Yuji underestimated him.

Except for a sentence in Chinese at the beginning, the communication between Yuji Yamamoto and Ge Xiaohua is all in English, so the communication is not hindered.

The two entered the room, exchanged some polite words, and began to talk about some forging experience, and opened up the conversation, the two seemed to have met each other for a long time, for Ge Xiaohua's coming to the capital this time, Yamamoto Yuji expressed his welcome , in his opinion, forging technology behind closed doors is not enough, it needs to communicate with each other, and he is also very curious about the ancient Chinese forging technology.

Ge Xiaohua also talked about his own experience, including the rhythm of beating, the temperature control of quenching, the angle of sharpening the knife and the rational use of machinery, etc., which benefited Yuji Yamamoto a lot. As opponents, the two are from different countries. Some historical questions, but they all have a profession, that is blacksmith!
The same profession has many common topics, not to mention that Yuji Yamamoto is not a traditional RB person, but a returned craftsman who has returned from studying abroad, so there will be more topics, and the more open he is after living in the United States for a long time.

After a long talk all night, Ge Xiaohua and Yamamoto Yuji changed from strangers to friends all of a sudden. It is hard to imagine that the hostile two will become a teacher and friend. It can be seen that forging technology does not distinguish between nationality and country.

"It's so late, Watson, I'm sorry to disturb your rest." Yuji Yamamoto looked at his phone. It was already around 3:[-] in the morning. Hungry.

Yamamoto called the hotel service, the two had supper, and then Yamamoto Yuji left. Knowing that Ge Xiaohua was going back to China, Yamamoto Yuji didn't know what to give, and he was quite reluctant. The two agreed that if they had time, Yamamoto Yuji Can come to China.

"In the quarterly championship competition, the elites really did their best. I have already seen the forging skills of Yuji Yamamoto. What other masters will be there?" Ge Xiaohua is now looking forward to the season's champion forging masters held by the United States USA. Not only did he observe During the whole process of forging the samurai sword, he also made friends with Yuji Yamamoto, a popular figure in the Yamamoto family. Although he could not communicate face-to-face with Master Masaosu Yamamoto, he believed that when he reached that level, he would have the opportunity to meet again.
