Master descends to earth

Chapter 90 Dragon Thorn
Xu Kui was very excited when he took out the ancient sword, put it in the furnace, and remelted it. He only knew a little about sabers, and he was a little nervous about having the opportunity to touch a new field.

Su Yuan pointed to the design drawing and explained: "Because the saber has various uses, its shape and design are completely different from traditional swords."

"The form of the blade needs to consider whether it has a toothed edge, which is subdivided into flat, half-toothed, and full-toothed edges, which vary according to the environment."

"For example, when cutting tomatoes, using a toothed knife can easily saw through without deforming the tomato due to pressure. But when using a flat-edged knife, in addition to sharpening the blade, you must first push and then pull."

"Experienced people know that the blade should be pushed forward first, and the characteristics of the flat blade suitable for flat cutting should be fully utilized first, and then pulled back, the incision made at this time will be beautiful."

Then he took out a data sheet and handed it to Xu Kui: "Nowadays, industrial cast steels have strict standards. In the AISI naming system, 10xx is carbon steel, and others are alloy steels. For example, 50xx series is chromium steel."

"In the SAE nomenclature system, tool steels are marked with letters. There is also the ASM nomenclature system, but it is rarely mentioned in the knife world. Usually the last number in the steel name is the type of steel. Carbon content, such as 1095 contains about 0.95% carbon, 52100 contains about 1.0% carbon, and 5160 contains about 0.60% carbon.”

The stupid man scratched his head, feeling a little headache from dozens of names, Su Yuan smiled and said: "There is no way, science is based on data, unlike traditional craftsmanship, which is all based on experience and feel, everything is quantified, so it can be standardized production."

Looking at the blazing stove is also the biggest problem restricting traditional craftsmanship. The taste of fast food is very different from that of chefs, but KFC McDonald's makes hundreds of billions of dollars in profits every year.

It all depends on experience, cannot be standardized, and cannot be mass-produced. Not only swords, but all traditional artworks face this problem.

Longquan is all traditional swordsmiths. They may only study how to make iron better, how to sharpen it by hand, and even concentrate on a sword for more than ten years.

However, high technology has spread all over the world, and the knife brands of developed countries such as island countries, Europe and the United States have long been popular among the people. Profit is the biggest driving force in today's society, and the decline of traditional craftsmanship can only be inevitable.

Su Yuan shook his head, everyone knows the truth, but it's hard to do it.A journey of a thousand miles begins with a single step, and it can only be done step by step.

"start!"

There were only three days, the time was tight and the tasks were heavy, and the next day and night were concentrated, and finally the saber embryo was created.

"I'll call you Dragon Thorn!"

Su Yuan was satisfied with playing with the golden light saber in his hand, it was bright and dazzling, its initial state was comparable to that of Long Yuan, even better than Long Teng Longwei.

Blow sharply!

Hard and soft!

Two flashes of white light flashed, and the dragon thorn erupted with astonishing light. First, a little bit of purple light appeared in the golden light, and then more and more purple light appeared, and finally spread all over the blade, becoming a veritable purple light saber.

Su Yuan laughed out loud, extremely satisfied. This is the second Ziguang Knife, which is fully integrated into the current design concept, and the manufacturing process is easy to handle, which fully proves that his strength has improved to a higher level.

After completing the dragon thorn, the two of them were going to Hong Kong Island. Huimei Yagyu hesitated a few times, and then mustered up her courage and said, "Master, can you take me to see it?"

Su Yuan frowned. The Su family's sword shop had just started, and she needed to manage many things, but seeing the little girl's face full of anticipation, she couldn't bear to refuse.

"By the way, didn't you say it was a world-wide expo?" Yagyu Huimei rolled her eyes and quickly recommended herself: "I understand four languages, and I can be a translator for master and brother."

"Yeah, why don't you take your junior sister?" Xu Kui said kindly, "I don't know bird language, so who knows what foreigners are talking about?"

Su Yuan couldn't help laughing, but he didn't expect this. Although he had passed CET-[-], he was useless.And it's not just English, there must be a lot of little devils and old men.

Can only nod, Emi Yagyu hurriedly bowed, and immediately packed her luggage. It was originally just two people, but it turned into a large group of bodyguards, and they directly took the first-class cabin and returned to Hong Kong Island.

Meeting with Huangfu River the next day, the old man looked at Su Yuan and Liu Shenghuimei who were being held up by the stars in black, and asked Shen Huanwen in a low voice: "Good guy, what's your background?"

Shen Huanwen shook his head, and said helplessly: "I heard that she is the eldest lady of the Liusheng family, who worships Su Yuan as a teacher in Longquan, so..."

"Liu Sheng's house?" Huangfu Jiang suddenly realized, and several people greeted each other, boarded the plane, and headed straight to Geneva. The destination was the headquarters of the famous knife brand, Vigo.

"Hitachi and Mitsubishi from island countries, Vigo and Weiss from Switzerland, Mad Dog, Butterfly, Kabbah, Advancer from the United States, and Cold Steel from Germany, all the top saber brands will participate."

Su Yuan leaned comfortably on the huge soft leather sofa, took the red wine from Emi Yagyu, and listened to Huangfu Jiang's introduction of the exposition.

As a collector, Huangfujiang traveled all over the world. He basically participated in the fair every year. He had a good network of contacts. He said with a smile, “The Swiss Victorinox officer’s knife is a good gift, and the pursuit of perfection is a consistent tradition. Therefore, it has been selected as a White House gift by several presidents. , the handle is engraved with the President’s signature as a gift to the guests. NASA also listed it as a portable tool for astronauts, and it is the big brother in the circle.”

"The Vigo brand has a long history and was founded in 1893. It is recognized as the best saber brand in the world. This exposition is held at its headquarters..."

"The Kabbah is most famous for its sabers, bayonets, and fighting knives. It was the standard configuration of the Marine Corps in the Korean War and the Vietnam War. A hunter once encountered a bear while hunting. He had no choice but to pick up the Union Razor Co. when he ran out of bullets. High quality hunting knives made to fight bears and save lives."

"After the catastrophe, he wrote in a letter that this knife can kill a bear (Kill a bear), but because of the low level of education, he wrote it as Kil a bar, and later it was abbreviated as Ka-bar, so the name Kaba His name will be known by all.”

If there is an old man in the family, if there is a treasure, people will see more when they live longer.Everyone listened to Huangfujiang's introduction with great interest, and soon had a general understanding of the saber circle.

"My personal favorite is Advance, although it is a small private company, it is dedicated to designing and manufacturing survival knives for use in harsh environments. The founders and operators are all retired military personnel. The core figure is Duane Dwyer , Paul Bos, the former is the founder and designer, and the latter is the master of heat treatment."

"There is also Mad Dog, although the name is not good, but the level is very high. Using 496-01 high-carbon tool steel developed by high technology, a very professional quenching-extrusion-tempering heat treatment process makes the blade achieve the ideal layer change hardness."

"The hardness of the blade is HRC62-63, which has excellent blade retention; while the hardness of the tip, spine and shank is HRC50-54, which maintains good elasticity and prevents the tip from breaking."

"Additionally, all the blades are electroplated, with a thick layer of hard chrome for great resistance to corrosion and wear..."

In the end, Huangfu Jiang concluded: "The so-called expo, to put it bluntly, is a PK competition between major companies, where the most advanced technology is used to wrestle wrists, mainly steel, which is the essence of competitiveness."
