took out the ancient sword, put it in the furnace, and re-smelted it, Xu Kui was very excited, he only knew a little about the saber, and he was a little nervous about having the opportunity to contact a new field.

Su Yuan pointed to the design and explained, "Because of its various uses, the saber is completely different from the traditional sword in terms of shape and design. ”

"The form of the blade needs to be considered 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, it is very easy to cut them with a toothed knife without deforming the tomatoes due to pressure. However, when using a flat-edged knife, in addition to the sharp edge, it is necessary to push and then pull. ”

"Experienced people know that you need to push the edge forward a little first, first make full use of the flat edge's characteristics for flat cutting, and then pull it back, so that the resulting incision will be beautiful. ”

He immediately took out a data sheet and handed it to Xu Kuidao: "Now there are strict standards for industrial casting steel, in the AISI naming system, 10xx is carbon steel, and the others are alloy steel, for example, the 50xx series is chromium steel. ”

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

The stupid big man scratched his head, dozens of names had a headache, Su Yuan smiled and said: "No way, science is based on data, unlike traditional craftsmanship, everything is quantified, so it can be standardized." ”

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

It is all based on experience, it cannot be standardized, it cannot be mass-produced, not only swords, but all traditional artworks face this problem.

Long Quan is a traditional swordsmith, and he may only study how to make iron better and sharper by hand, and even concentrate on a sword for more than ten years.

And high-tech has spread all over the world, island countries, Europe and the United States and other developed countries knife brands have long been deeply rooted in the hearts of the people, profit is the biggest driving force in today's society, the decline of traditional craftsmanship can only be inevitable.

Su Yuan shook his head, everyone understands the truth, but it is difficult to do it. A journey of a thousand miles begins with a single step, and can only be taken step by step.

"Let's go!"

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

"I'll call you a dragon thorn!"

Su Yuan was satisfied with the golden light saber in his hand, bright and dazzling, and his initial state was on par with Long Yuan, and it was better than Long Teng Longwei.

Blow-hair!

Rigidity and softness!

Two white lights flashed, and the dragon thorn burst out with an astonishing light, first a little purple light appeared in the golden light, and then more and more purple light, and finally spread all over the entire blade, becoming a veritable purple light saber.

Su Yuan laughed, extremely satisfied, this is the second purple light knife, which is fully integrated into the current design concept, and the building process is easy, fully proving that his strength has reached a higher level.

After completing the dragon thorn, the two were about to go to Hong Kong Island, Emi Yanagi hesitated a few times, plucked up her courage and said, "Master, can you take me to have a look?"

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

"By the way, didn't you say that it was a world-wide exposition?" Emi Yanagi rolled her eyes, and quickly recommended herself: "I know the four Chinese dialects, and I can be the translator of the master and senior brother." ”

"Yes, why don't you take your junior sister with you?" Xu Kui helped to say good things next to him: "I don't know bird language, who knows what foreigners are twittering?"

Su Yuan smiled dumbly, but he didn't expect that although he was level 4 in English, he was useless. And it's not just English, there must be a lot of little devils and old hairies.

could only nod, Emi Yanagi quickly bowed, and immediately packed her luggage, it was originally just two people, but it turned out to be a large group of bodyguards, directly wrapped in first class, and returned to Hong Kong Island.

The next day, he met with Huangfu Jiang, and the old man looked at Su Yuan and Emi Yanagi, who were held by the stars of the men in black, and asked Shen Huanwen in a low voice: "Good guy, what is the origin?"

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

"Liusheng family?" Huangfu Jiang suddenly realized, several people said hello, got on the plane, and went straight to Geneva, the destination was the headquarters of the famous knife brand, Weigo.

"Hitachi and Mitsubishi in the island countries, Wigo and Weis in Switzerland, Mad Dog, Butterfly, Kaba, and Advance in the United States, as well as Cold Steel in Germany, several top saber brands will participate. ”

Su Yuan comfortably leaned on the huge soft leather sofa, took the red wine handed by Emi Yanagi, and listened to Huangfu Jiang's introduction to the expo.

As a collector, Huang Fujiang flies all over the world, basically participates in the expo every year, and is very familiar with the network, and said with a smile: "The Swiss Victorinox officer knife is a good gift, and the pursuit of perfection is a consistent tradition, so it has been selected as a gift by several presidents for the White House, and the handle of the knife is engraved with the president's signature to give to the guests." NASA also lists it as an astronaut's carry-on tool, the big brother of the circle. ”

"The Vigo brand has a long history, founded in 1893, and is recognized as the best saber brand in the world, and this fair is held at its headquarters......"

"The Kaba is most famous for its sabers, bayonets, and fighting knives, which were standard equipment for the Marines in the Korean War and the Vietnam War. A hunter once ran into a bear while hunting, and when he ran out of bullets, he had to pick up a high-quality hunting knife made by Union Razor Co. to fight the bear and save his life. ”

For the rest of his life, he wrote in his letter that the knife could kill a bear, but because of his low level of education, he wrote it as Kil a bar, and later it was abbreviated to Ka-bar, so the name Kaba was praised by everyone. ”

There is an old man in the family, if there is a treasure, people will see a lot when they live for a long time. Everyone listened to Huangfu Jiang's introduction, relished it, and soon had a general understanding of the saber circle.

"My personal favourite is Advancer, a small private company that designs and manufactures survival knives for use in harsh environments, founded and run by retired military personnel, with Duane Dwyer at the heart of the company, and Paul Bos, the former as the founder and designer, and Paul Bos, who is a master of heat treatment. ”

"There are also mad dogs, whose names are not good, but at a high level. The high-tech development of 496-01 high-carbon tool steel, a very professional quenching-extrusion-tempering heat treatment process, so that the cutting edge can achieve the ideal layer hardness. ”

"The blade hardness is HRC62-63 for very good edge retention, while the tip ridge and shank core are HRC50-54 for good elasticity and prevent the tip from breaking. ”

"In addition to this, all cutting edges are plated and a thick layer of hard chrome alloy is highly resistant to corrosion and abrasion......

In the end, Huang Fujiang concluded: "The so-called expo, to put it bluntly, is a PK competition of major companies, and the most advanced technology is wrestling, mainly steel, which is the true meaning of competitiveness." ”
