After thinking of these techniques, Marin quickly wrote all of them in his notebook, and then went to the forging base near Lair City in the south to let the craftsmen cooperate and try new methods and cast new sabers.
Of course, first, Marin asked the steel mill to get a batch of medium-carbon steel bars. Then, the craftsmen responsible for building swords were asked to forge the saber.
It is not difficult to build medium-carbon steel bars, because the medium-carbon steel produced by Marin's steel factory has been refined and cleaned by slag-making agent, so there are few impurities in the steel bars and there is no need to be hammered and forged like oriental craftsmen to knock out the impurities inside.
For knife casters, they only need to put in effort to beat the medium carbon steel bar into the shape of the blade. The knocking process is also a process to make the inside of the steel itself closer. In later generations, in order to forge qualified aircraft wings, a water press of tens of thousands of tons was even needed to forge the aluminum alloy wings so that the wings were strong enough. Otherwise, if the wing strength was not enough, the wings would fall off when the aircraft flew...
Therefore, the forging process is essential for making knives. Because the forging process can make the loose structure inside the steel during the original casting become tighter and the performance is enhanced.
Here we have to mention the difference between casting cannons and forging cannons. Have you seen the Red Cannon? The pipe wall is so thick, it looks very heavy at first glance... That is why ancient steel technology was backward and had not been forged. Although the ancient cannons' pipe walls are so thick, the chamber pressure that can withstand may not be as large as those with thinner pipe walls in later generations.
The rise of the German Empire was dependent on Krupp's steel cannons. The reason why Krupp's artillery was powerful was because the Krupp's artillery was forged cannons and could withstand a large chamber pressure. Before the Franco-Prussian War, forged steel cannons were rare. In the American Civil War before the Franco-Prussian War, the main artillery Napoleon cannon was a typical casting cannon.
Krupp's artillery first uses a large tonnage forging machine to vigorously forge the steel columns, making the internal crystal structure of the steel more tight, and the ability to withstand chamber pressure is greatly increased.
The Krupp Company only started drilling with a drilling rig until the steel column was forged. Although it became difficult to drill holes for forged steel columns, the barrels obtained had greatly improved their resistance to chamber pressure. Moreover, the cannon cannon can also be made lighter. Otherwise, if casting, it would be necessary to make it as thick and bulky as the Red Barbarian cannon...
Then, the French army, which still used cast guns, were beaten by the Krupp forged cannons of the Prussian army... and then, forged cannons became popular in Europe, and cast cannons withdrew from the stage of history...

In order to improve the metallic properties of the blade and plate armor, at the beginning, the steel bar was actually sent to the hydraulic forging hammer on the artificial reservoir for strong forging. Then, the medium-carbon steel bars forged by the hydraulic forging hammer will be beaten by the knife caster with a blacksmith hammer to adjust the appearance. After all, the hydraulic forging hammer is very rough and sometimes it will deform the steel bar too much. Therefore, the blacksmiths need to readjust the shape by heating forging...
With the forging of the knife casters, the steel bars were beaten more and more like swords...
When the blade is basically formed, it is the carburizing stage. Marin specially brought his own soybean paste made from soybeans produced in America. Combined with charcoal and soil powder, he began the process of solid carburizing on the surface of the blade called the "stewing steel method"...
After several hours of stewing in the crucible, Marin felt that the carburization was almost done, and then salt quenching and oil quenching began.
Marin still uses horse urine when quenching salt. After all, although it is salt quenching, Marin does not know whether there are other ingredients in the horse urine that are beneficial to swords. Therefore, when quenching salt, Marin directly uses horse urine. However, in order to enhance the effect, he also added salt to the horse urine to make the salt concentration larger and enhance the effect.
As for oil quenching, it is definitely to use whale oil that cannot be eaten. There are many things in Marin, so it is not a pity to use them. Now, the number of whaling teams on Newfoundland has reached 5, and whales are often hunted. If Marin hadn’t limited their number of hunting, it would have been estimated that those whaling teams could have hunted whales every day. After all, there are very few whales in the world now, and the fishery resources in Newfoundland fishery are so rich that there are many whales here, and there are countless whales catching...

After working hard to get the new saber in the beta, Marin couldn't wait to test the effect for the guards. This time, the new sabers were created in total, one for slashing with high-carbon steel sabers, and the other for slashing with this grandma with an ordinary European iron knife...
As a result, Marin was surprised to find that the new saber that had been complicatedly processed was indeed extraordinary...
The result of chopping with the high-carbon steel saber is that the high-carbon steel knife is broken, but the new saber is cut out of the gap. After all, the high-carbon steel knife itself is very hard... When chopping, the high-carbon steel knife is easy to fold just over, and the new saber rebounds back after bent, but it is not broken in the end, but the hard blade of the high-carbon steel knife is cut out of the gap.
When it comes to the traditional European iron knife, it will naturally win a great victory and completely crush it. The new saber not only cuts off the ordinary iron knife, but it is only scratched with a scratch mark...
...
After testing, the new saber retains the advantages of the old high-carbon steel knife's blade's high blade hardness, but at the same time the toughness of the blade body has been greatly enhanced. It can actually win when chopping against the high-carbon steel knife. Not to mention those iron knives in the current European era.
Karn, who was in charge of the test, suddenly his eyes lit up and snatched the third saber that had not been tested as his own sword. After all, for generals, a sword is very attractive.
Marin shook his head, he did not compete with Kahn for this knife. After all, this new saber, strictly speaking, is just a low-cost medium-sized product, a large-scale product used to widely ship cavalry, not a high-quality product.
In fact, if Marin wanted a sword, he could send someone to Japan to hire a senior sword caster to create a new swordsman for it using stacking forging.
What's more, the natural pattern steel in India has not yet been discontinued. If you want a treasure knife, go to India to buy a batch of Uzi steel and come back.
"Oh, I almost forgot that I can buy some umz steel when I send a fleet to India this time!" Marin slapped his head and quickly sent someone to notify the trade representative Draka who was preparing to go to India. He ordered him to purchase a batch of natural umz steel after going to India and then use it to build a treasure knife.
Natural Uz steel, coupled with Marin's advanced carburizing and quenching methods, will inevitably get advanced treasure knives...
