"Tang Liudian" volume 16 arsenal order Cheng Zhi Zhangzhang recorded: There are four knife systems, one is called the Yi knife, the second is the barrier knife, the third is the horizontal knife, and the fourth is the Mo knife.

Today, the term "Tang knife" is the general name of the four saber systems of the Sui and Tang dynasties, and generally refers to the Tang horizontal knife.

The modern commonly known "Tang knife" is mainly a concept promoted by some sword traders in the mainland: its narrow and straight blade, small blade, and long handle shape. The direct prototype is the RB Shosoin Collection, which was imported from the Tang Dynasty thousands of years ago with a "gold and silver Tang sword".

The knife shape of the Tang knife comes from the Han ring head knife, and most military Tang knives in the early stage retained the ring head, but also had a straight blade.

As an army sword, the biggest role of the Tang knife is to fight, and its production process is strict, and it also takes into account two other key characteristics when fighting: that is, armor piercing and durability!

Armor piercing requires hardness and a narrow edge, and durability requires toughness, so the Tang knife adopted the world's most advanced steel-clad technology at that time.

Wrought iron is used as the outer skin, hundreds of steels are sandwiched in the middle, and part of the cutting edges are partially quenched by local quenching technology, that is, covered with soil and burned edges.

The blade is hard enough to chop and pierce armor, and at the same time, the toughness of the blade is not deformed!

And durable: this is the biggest difference between a horizontal knife and an RB knife!

In ancient times, there were very few iron armors, and the armor of those high-ranking samurai looked exaggerated, but many of them were made of bamboo!

The ancient RB top katana was extremely sharp, but when it started, it was not uncommon for a Japanese general to stick three or five swords in his waist and two more samurai swords on his back, and then his followers followed to help take a few spare katanas, and then charge into battle!

Not to mention that a katana is used for several years, it is common to break three or five or seven after a battle.

The RB people remember it in their own history.

So why have so many ancient katanas been preserved?

The first is the small scale of the old war in the RB homeland, and the second is that many famous knives are treasured and ornamented by the upper class.

So how to distinguish a Tang knife from other straight knives?

Generally, the simple way to distinguish other straight knives similar to Tang knives is: the tip of the knife is angular for Tang knives!

There is a blood groove, the tip of the knife is semicircular, and more than one-half to one-third of the blade area is a straight knife.

In fact, the Tang Dynasty Huaxia also had a narrow scimitar, which was painted in the unearthed tomb murals, so it is nonsense to say that the devil invented the curved blade to increase the lethality!

Then why are the horizontal knives of the Tang Dynasty unearthed all rigid and straight?

Because the war and opponents faced by the Tang Dynasty are not the general arms fights of the domestic princes and gang fights!

The curved katana is extremely lethal against the human body without iron armor!

But against an ironclad opponent, the curved knife will not work.

Armor piercing requires a straight blade!

That bearded uncle is at most a military character expert, and he has a very accurate grasp of the price of the devil's saber, but he is a Westerner after all, and he recognizes a top-level national treasure-level Chinese Tang Dynasty horizontal knife as a devil's katana!

He may not have known that there was a horizontal sword in Huaxia, but it is more likely that he doesn't know what the Tang Dynasty is!< br&gt;

Don't be surprised that in the 80s, many Americans' understanding of Huaxia was limited to many movies that scandalized the image of China, and they still thought that Chinese people were still wearing melon skin hats at this time!

Not to mention the United States, many of the Xiangjiang movies in the eighties and nineties are still scandalizing the mainland.

Far from it.

How did Zhang Nan recognize that it was a horizontal knife in the Tang Dynasty?

The wooden handle that cannot be easily removed, the straight scabbard, and the mottled marks on the head are not caused by poor long-term preservation, but because they have been too long!

Until now, Zhang Nan has not been sure whether the knife of this horizontal knife is equipped with a back.

More than a thousand years is too long for a steel knife!

If the knife outfit was newly equipped eight hundred years ago, after such a long time, Zhang Nan would not be able to see it!

But the blade itself must have been made in the Tang Dynasty: not only the steel process, but also the words "Shaofu Supervisor" on the side of the blade!

Shaofu Supervisor, the name of the central bureaucracy in ancient China.

Shaofu is an ancient Chinese official name that appeared earlier and lasted for a long time, and the positions of the past dynasties were different.

After the Tang Dynasty, it was mostly called the Shaofu Supervisor, and the Yuan Dynasty was abolished.

Huaxia was the first Shaofu to be established during the Warring States Period, in charge of the handicraft industry and the private estate of the monarch.

The Shaofu of the Tang Dynasty was only in charge of all kinds of workmanship, and ordnance manufacturing was also in it.

Moreover, the Tang Dynasty had strict regulations on the creation of weapons by the people!

For more than 100 years from Li Yuan's proclamation as emperor to the Anshi Rebellion, the Tang Dynasty strictly forbade the people to build weapons! The weapons in the state treasury and the government treasury were all made by the manufacturing institutions specially set up by the central and local officials at all levels.

There are also strict regulations on the types and quantities of weapons that are allowed to be produced by the manufacturing institutions set up by each level of government.

In addition, the Tang Dynasty had relatively uniform requirements for the specifications of weapons, which also made it possible to use weapons made in various places.

Because in the past 100 years, the Tang Dynasty had a prosperous economy, a strong military, a stable domestic order, and no war in the Central Plains for a hundred years, so there were few people who violated this law, made weapons without permission, and defended the law.

For more than 100 years, the weapons of the Tang Dynasty were all made by the government.

And this knife is engraved with "Shaofu Supervisor", indicating that this knife should have been made in the ordnance workshop directly controlled by the central government of the Tang Dynasty. The total length of the handle is about one meter, which belongs to the category of "big horizontal knife" in the Tang Dynasty.

Uncle Beard said that he bought this knife from someone else, but what happened before?

Sorry, he didn't know!

Zhang Nan is estimated to be near Chang'an, after this knife was manufactured, I don't know what the reason and process are, this knife was brought to RB As for how this knife got to the United States, there is a chance that the American soldiers collected it in the devil's homeland, and that person doesn't know the true value of this knife!

It stands to reason that such a horizontal knife in the Tang Dynasty can be preserved until now, and it must have been circulated in an orderly manner for thousands of years and has been carefully maintained, otherwise it will not be preserved at all.

But why did this knife not have a good reputation before and was not preserved as a national treasure by the little devils?

Maybe it's a family secret?

Maybe there's something wrong with the way it came from, causing the holder to keep it secret?

Maybe......

Who knows!

Zhang Nan probably won't be able to figure out this question for the rest of his life, and he doesn't need to figure it out

Moreover, in addition to the RB people, other countries, including Huaxia, still have some doubts about whether the Tang swords and Sui swords preserved in RB are the real Tang swords.

It's not that I suspect that there is a problem with the age of those knives, but the place of origin!

After RB brought the Sui and Tang knives back to China, they were called "Tang Dadao". Also imitated in China, these straight knife imitations are called "Tang style broadswords" by today's RB people.

But I haven't heard of those knives more than a thousand years ago with inscriptions!

Zhang Nan was very tired, but he still had to thank Nicole for the third time: "If you hadn't pulled me to this flea market, I would have missed it!"

Maybe someone who doesn't know how to buy it as a plaything and throw it in a storage room or even a dumpster!

So, thank you again!

After a while, I will give you a gift, please don't refuse it then. ”

This is a Tang horizontal knife that has never been recorded or appeared, Zhang Nan's guess is not out of thin air: if Zhang Nan did not appear here today, it is very likely that it will be completely dusted, and even thrown into the landfill store and buried a few years later!

Americans love that new katana, not unpretentious it!

As for giving Nicole a gift, Zhang Nan considered not giving anything, but something else: in fact, it was also mutually beneficial for him and Nicole.
