It is obvious that it is a wrong decision to let Wang Qibu join the chat now. The gap in vision has been decided from the beginning. This is somewhat embarrassing result now. The reason why this scene is not that Wang Qibu deliberately shows it. He is just using personal experience examples to express a simple fact. As for what others think, believe it or not, it is not something he needs to care about.

"By the way, Brother Zhou, I remember you said that the knife I saw at my company last time was good. I happened to find someone to see the office feng shui. The master said that my knife was not suitable. I just took it back as soon as I thought about it. You can take it away when you leave tomorrow." It was wise, Cao Yan changed the topic.

"Oh? Then thank me, brother. It's true. I've been thinking about it for several days since I came back from you." Zhou Qi said, not much social factors, which is really an unexpected surprise for him.

"What kind of knife? Brother Bao Cen, since you are all at home, let everyone hug you first. Is it good to have a sense of gain?" There are no soldiers who don't like swords and guns, so when they hear that there are good swords, Xu Yunlong was the first to sit still.

"Yes, Brother Bao Cen will take it out and let everyone love to see."

"The thing that Brother Zhou can think of is definitely a treasure. Brother Bao Cen, please don't hide it."

Facing everyone's cheers, Cao Yan was really not good to take it out. Otherwise, if the knife was sent, but if others thought he was stingy, he would have died unjustly. The villa was originally a semi-club, so there were many errand runners who accompanied him. Not long after, a few feet long mahogany box was carried out by a staff member.

Cao Yan took it, placed it on the table and then opened the lid, and a sharp blade filled with sheath blade was presented in front of everyone. Wang Qibu found that as the lid was opened, Zhou Qi's eyes lit up. It seemed that he really liked it.

"Is this a samurai sword?" After careful observation, Kobayashi said uncertainly.

"It's Tang Dao." Zhou Qi said, with a slightly unpleasant expression. In fact, there are also people who know swords, such as Cao Yan, Wang Qibu, Shen Qingge, Yue Xiaochen, Xu Yunlong, etc. These people stubbornly believed that the Japanese had shamelessly copied the great Tang Dao, and they also made a toy like Bushido. As a result, people nowadays don't know Tang Dao, but they often messed up Tang Dao with that toy, which is an insult to Tang Dao. This makes them particularly angry.

"Brother Zhou, I'm sorry, I really don't know. But is there any difference between these two types of swords? Can you tell me?" Feeling the unpleasantness in Zhou Qi's words and the negative atmosphere in the scene, Kobayashi hurriedly said. This is not how he wants to know Tang Dao's knowledge. The bigger reason is probably to appease Zhou Qi's emotions. I have to say that he is smart and asking for advice is indeed a good way.

"Haha, it's okay, everyone doesn't understand anything. In fact, generally speaking, the sword body of the Japanese samurai sword has a certain arc, while the Tang sword mostly adopts a straight body shape. This is the easiest way to distinguish it. However, in fact, there are also some ninja swords in Japan that adopt a straight blade shape, and there are also benders in the Tang sword. However, this only accounts for a small part of it. It is sometimes not reliable to distinguish between the samurai sword and the Tang sword according to whether the blade is bent or not. A more profound method is that the blade area of ​​the Japanese sword generally accounts for more than half of the blade area, while the blade area of ​​the Tang sword is generally about one-quarter, and the axe blade shape is used. Why is this happening? This is determined by the battlefield environment. On the Japanese battlefield, metal armor is definitely a rare thing, or in other words, except for the extremely noble generals, there will be a heart-protecting mirror.

In addition to things like that, other warriors or soldiers basically only wear a layer of cloth and go to the battlefield. In this environment, the work of the knife is mainly about cutting meat, and the sharper the better. In order to meet such requirements, it is natural to expand the blade area to half of the blade area. On the ancient battlefield in China, it is more common to encounter a heart protection mirror, a copper helmet, etc. in the sword. In the face of this situation, the blade cannot simply pursue sharpness, but also take into account the armor-breaking ability; and the axe blade is a reflection of this requirement. Therefore, compared to the Japanese samurai sword, the Tang sword is something that men play. In ancient times, the other party carried a sledgehammer worth hundreds of pounds, and you took a simple Tang sword into battle, which itself requires great courage." Sure enough, Zhou Qi didn't say anything else. On the contrary, he patiently explained to Kobayashi.

"In fact, not only in appearance, but also in the production process, Tang swords also have special forging methods compared to Japanese swords. Qibu, I think you are staring at this sword with your eyes, it seems that you must have studied Tang swords. So do you know this method?" When you meet someone who loves swords, such a competition is very normal. Especially today, Wang Qibu is recommended by himself no matter how he steals the limelight. He can't be neglected.

"Haha, Brother Zhou, you're testing me. But I really know this Tang sword. Forging Tang sword requires first two pieces of hard steel, which are made by folding method. When creating, the temperature is controlled between 750-800 degrees, the number of folds is about 15 times, and there is a dazzling layer. Then, two pieces of hard steel with a dazzling layer are clamped together with a soft steel, heat it to about 1300 degrees, and then forged it to turn three pieces of steel into one piece of steel, and then extend it to the basic shape of the knife. At this time, the steel knife has been heated to 130 degrees, and then forged it to make three pieces of steel into one piece of steel, and then extend it to the basic shape of the knife. At this time, the steel knife has been heated to 130 degrees.

0 degrees, the surface has been decarbonized and the hardness has become smaller, so it has to be treated with charcoal seepage to strengthen the surface hardness. However, this process seems to have been lost now. After that, it is the quenching mentioned earlier, it is plastic surgery, polishing, and polishing. This is the traditional famous three-piece combination. Let’s talk about Japanese knives. Japanese knives are made of a piece of jade steel. Just like the method of making hard steel in Tang knives, after being beaten, they are made into steel blocks of about 20cm. A V-shaped groove is opened on the side where the back of the knife is ready to be made, and the depth is the whole piece of steel.

Then put a piece of mild steel, and then heat the steel to between 750-800 degrees. It is the same as the folding and forging temperature, and it is the shape of a knife, and then it is covered with soil and burning the blade. The method of covering soil is different from that of China. The Chinese Tang sword is covered with soil at one time, and Japan covers soil many times, each time is very thin and has layers, so there is a very obvious sea pattern when the Japanese sword burns it. This is not the pattern of folded pattern steel. The real folded pattern steel is very
