After the old shopkeeper and Ruijin Richard glanced at each other, they also nodded, and both of them put on their gloves and began to observe carefully, maybe there was something special about this thing.

"If I'm not mistaken, this sword should be a Chu sword, a sword worn by a sergeant, not used for fighting, just a status symbol, but this sword handle and blade are very rusty, if you want to polish all the rust, I'm afraid you will damage the sword body." Rygin Richard said after some observation for himself.

"Yes, that's my opinion too. The old shopkeeper also lightly slashed the sword with his gloved hand a few times, and then nodded and said: "It's not cost-effective to polish this thing, by the way, Boss Zhang, you haven't said how much this thing cost?"

"It's not expensive to buy, only five hundred yuan, don't you all think this rust can't be polished? But if you don't polish it, how can you know what is under the rust?" Zhang Tianyuan was really stunned, the reason why he bought this sword was mainly because he took a fancy to what treasure should be in this sword, but if it wasn't polished, how could this thing be taken out?

As for if the things on this sword are polished off, he doesn't care at all, even if he destroys this sword, it doesn't matter, anyway, this thing is already so rusty, it's not worth a few dollars at all, if you continue to let the rust continue to be stored like this, it is estimated that it won't be long before this sword will completely turn into patina, so it's better to try polishing it yourself.

Hearing Zhang Tianyuan's words, Ruijin Richard hurriedly waved his hand and said, "Don't, don't." This is a sword from the Spring and Autumn Period and the Warring States Period, once it is sharpened indiscriminately. ...... would spoil the good stuff."

"Of course I know this, but I don't need to do it this way. What else can I do, I can't just collect it, can I?"

Although Zhang Tianyuan is not good at appreciating and collecting swords, he also knows that if an ancient sword like this is blindly polished, there will definitely be problems, and it will easily destroy the sword.

It was precisely because he knew this that he did it with the idea of simply destroying this sword, although Chu Jian was good. However, it was rusty, and he wanted the dazzling thing inside.

However, the old shopkeeper obviously thinks the same as Ruijin Richard, he also does not agree with Zhang Tianyuan's indiscriminate polishing, although he has not played with swords in recent years, but when the antique market was not as standardized as it is now, he still had a lot of opportunities to play, and he knew more about this knowledge.

"Boss Xiao Zhang, this sharpening sword, if it's just an ordinary sword. It's okay, you can polish it with a grinding stone or sandpaper, but like this ancient sword, I still recommend asking a professional to polish it. If you don't do that, you will destroy the hard steel covering the surface of the sword, and when the time comes. This sword is a bit nondescript......"

"Yes, Mr. Zhang, although my vision may not be as good as yours. But about the maintenance of swords, I may still know a little better than Mr. Zhang. That's what I think. Especially this Chu sword, because it is used for wearing, its own shape is very unique, if it is polished indiscriminately, there will definitely be problems. Ruijin Richard said.

"Director Richard has sharpened swords before?" asked Zhang Tianyuan with interest.

"Of course, as a sword collector, if you don't know how to sharpen swords, it's unimaginable, but my level is still too low, so I usually ask professionals to help me sharpen swords. Chinese swords are not only weapons in the era of cold weapons, but also collector's items of modern people. It has almost become a belief and worshipped in the hearts of the Chinese, which is why it has now produced its unique grinding technique. Through the grinding process of the grinder, the unique forging pattern texture of the sword is revealed. It also fully expresses the elegance, dignity and dignity of the sword. Ruijin Richard nodded.

"So mysterious, huh?"

"This is not mysterious, this is a kind of respect for the sword! Don't be in a hurry to sharpen an ancient sword in your hand, it is necessary to take the time to observe the sword in your hand. A sword is rusted and pulped, whether the sword bar is bent, the blade is cracked, etc., before grinding, do 'metallographic detection', non-invasive electronic ultrasonic scanning projection, etc., so that the information of the sword will not be destroyed, and it will help to protect and judge the age of the sword and the forging at that time, just like a dialogue with the ancients...... New swords can also have flaws due to the craftsmanship of the swordsmith, and after thorough observation and study, it is possible to avoid the failure of forging or quenching and prepare for grinding in advance......"

Through Guò Ruijin Richard's calcite, Zhang Tianyuan now understands that this sword is the best, but maintenance may be more important than trading.

In fact, this is a bit similar to buying a car, many luxury cars may not be difficult to buy, but maintenance is very expensive, many people can afford to buy a car, but they can't afford to maintain it.

According to Ruijin Richard, this grinding process is taken to the extreme in Japan.

In Japan, sword sharpening can be divided into "Shichiken" and "Shijoken". "Shijiken" is the basic shaping and grinding of the sword with a stone, and "Shijoken" is the process of fine grinding of the sword to further beautify the blade.

The development of the grinding process was based on the Honami stream of the Honami family. The ancestor of the Ami family, Myomoto, was from the Northern and Southern Dynasties of Japan, and their family served the Ashikaga family, the Toyotomi family, and the Tokugawa family for generations, and carried out Japanese sword grinding and appraisal work, among which the Honami Mitsuyue was the most famous.

You know, in Japan, the income of an excellent grinding master is very high, because slow work produces fine work, many things have to be done slowly, this fine grinding work, the required procedures are very complicated, basically can be regarded as an art, really handle a sword, light yì It takes nearly half a month.

"Teacher Zhang, you don't understand this aspect, so you may not know the importance of grinding, if you mess around, it is likely to destroy the shape and pattern of the sword itself, making the sword completely become another thing, I have encountered such a thing before. Rickin Richard fell into the memory.

"When I went to Japan to film, I went to a village to rest and fell in love with a Japanese sword. I thought it was very good, so I decided to buy it. But I was there alone, so I didn't have any money with me. I asked the man to help me keep the knife first, and I went back to get the money myself, and I blamed me for being confused at the time, and I was supposed to call the assistant, but as soon as I went back, the problem arose. ”

"What's wrong?"

"Alas, there is a Chinese idiom called painting snakes add to the feet, and when I went back to get the money, the owner of the knife actually raised the price of the knife. I thought I was going to give him 200,000 yen, but he greedily wanted 500,000 yen, I didn't give it, he originally agreed, but who knew that he actually made such a thing, if I knew, I would rather give him 500,000 than let him be so bad!"

"He's not going to polish that knife for you like new, is he?"

"Alas. That's right, he really made me a new one, and although there was some rust on the original sword, it looked very quaint and sharp. At first glance, you can tell that it is an ancient sword, and there are some special patterns on it, which is very exquisite. But who knew that this guy could me off and not only sharpen his sword. And the handle and scabbard have been replaced, and all have been replaced with new ones. ”

"It's more than just a snake to add to it. When you say this, I am reminded of a story circulating on the Internet, which is about a man who bought a suit and originally planned to apply for a job to wear it the next day, but his grandmother had never seen this kind of dress, and she was afraid that her grandson would be cold, so she re-cut the top of the suit and made it into a Zhongshan suit. It made this benevolent brother laugh and wanted to cry, and he had no choice but to spend a lot of money to buy a suit. ”

"Alas, Mr. Zhang, you don't know, I was angry at the time, and I was almost beaten by the man who caught him. That guy didn't know what he had done wrong, and wanted to sell it to me for 500,000 yen, but I didn't give me a penny, so I turned around and left. ”

Ruijin Richard sued Zhang Tianyuan about this, in fact, he wanted to tell Zhang Tianyuan how important the maintenance of this sword is, if it comes randomly, it will really ruin good things.

According to Ruijin Richard's Jianyì, if it is an antique sword, as long as the rust is not very heavy, don't make a big fuss, you can ask a professional grinder to carry out local rust removal work, don't mess around yourself, I have seen some people, just got a good thing, feel that the rust on it is not good-looking, so they use rust removal oil to remove rust, which is not wrong, but you must know that for the weapons before the Song Dynasty, especially the wrong gold and silver swords, once the rust removal oil enters the gap, it will expand, and then it will destroy the original structure.

"It turns out that there is so much attention to this apology and maintenance, I don't know very well. "Zhang Tianyuan is the first time to buy something like a sword, so it's normal to not know, the ancient swords he saw first were actually those in the Terracotta Army, anyway, those things looked very well preserved, the cold light was shining, there was no rust at all, but he didn't know how to get it.

"These are actually nothing, as long as you are willing, Mr. Zhang, it is estimated that you will understand soon. ”

"Director Richard, since you are so proficient in sword maintenance, it stands to reason that you shouldn't be able to see that Tang knife is fake? Now you can't detect where the fake is?" Zhang Tianyuan was a little puzzled, if Ruijin Richard knew so much about swords, then he should definitely be able to identify the authenticity of that thing, how could he chase him out and ask him to identify it, this is really a strange thing.

Ruijin Richard shook his head and said with a wry smile: "I know how to maintain, but I may not know how to appreciate it, so I should ask Mr. Zhang to explain it, so I will die." ”

To be honest, Ruijin Richard is still holding some luck even now, he just wants to hear where Zhang Tianyuan judged that this knife is fake, if it is unreasonable, then maybe Zhang Tianyuan judged it wrongly, and even if he was not deceived, it was just a misunderstanding.

Of course, this fluke came from the fact that he really didn't want to believe that Lilith would cheat on him with others, but it was only a little bit of luck.

In fact, he is afraid that deep down he understands it, most of what Zhang Tianyuan said should be true, but he still can't accept it in his heart. (To be continued......)
