Walking on the road, the beautiful woman asked Topaz, "Why is the Persian curved sword on its head bent and so beautiful?"

Topaz said: "Generally speaking, Persian swords can be divided into straight swords and curved swords, and the high-grade ones are carefully forged by hand with high-quality steel. The pen & fun & pavilion www.biquge.info straight sword to stab the enemy, and the curved sword is both stabbing and splitting (similar to a single-edged saber in the general sense, but the head of the sword is like a double-edged sword). The sword is made of ivory, some are made of animal horns, some are wrapped in shark skin, and some are inlaid with jewelry, gold and silver and other ornaments on the saber to show the identity and status of the owner. The handguards are also delicately engraved and gilded. The scabbard is usually made of thin iron plate plated with gold and silver, or covered with leather, and the inner sheath is lined with leather on both sides to protect the sword. The pattern on the sword, the blade of the blade after fine grinding to show a beautiful texture, but none of the same, the surface pattern of the sword can be divided into two categories: one is the flowing water pattern, the flowing water pattern can be divided into wave pattern and whirlpool, the other is the cloud pattern, can be divided into the cloud pattern (like the clouds rolling in the sky one after another) and the floating cloud pattern (like the clouds in the clear sky, rare), with the cloud pattern is the most difficult to cast. In the pattern sword, in order to reflect the effect of the pattern, the pattern is also divided into two types, namely the yin pattern and the yang pattern. The Yin pattern mainly relies on human hands through coarse grinding, medium grinding, fine grinding and very fine grinding to show the folded pattern faintly, and the longer the time, the more the pattern appears. Yang pattern is the blade body after fine grinding, with a warm acid dilution solution special formula cleaning, its texture color black and white distinct, and the yin pattern of the looming, light and elegant comparison, can be said to be two shades suitable, each has its own characteristics. The real pattern blade formed by folding multiple layers of steel, in addition to the beautiful surface pattern, the blade body is also very tough, and its edge is very fine jagged, so it is easy to cut soft things, and the drag knife is extremely smooth. The blade maker heats the bar steel for hammer forging and repeatedly folds it to precipitate out the debris in the raw material and make the steel symmetrical, and the pattern is also revealed at this time. During the smelting and forging process, the master observes the fire with tongs in one hand, and points to the place where it should be hammered with a small hammer with the other hand, and the apprentice uses a sledgehammer to hammer hard, so that the hammered steel has been reduced to one-third of the original weight. This kind of hammering method is not good for many times, whether it is made of steel depends on experience and feeling. Forging requires rich experience, a little careless, the steel can not be melted or cracked, that is, all scrapped. The maximum number of folds of the patterned sword is 768 layers eight times, and because the thickness of each layer is too thin, most of them have been fused, and the blade is only about 40 mm wide, so the number of layers is really difficult to distinguish. Practical and aesthetically pleasing, 384 floors are the most suitable, that is, 100 steel. Patterned swords have the ability to cut through iron, cut gold and jade, and other swords come into contact with it, and there are few that are not cut or damaged. We have cast bronze pattern swords very early, and there have been many famous swords in the past dynasties, such as Ganjiang, Mo Xie, Long Yuan, Tai'a, Zhan Lu, Yu Gu, Juque, etc. During the Spring and Autumn Period, the two swords "Ganjiang" and "Mo Evil" cast by the famous sword master of Wu Guozhu, the former sword body is covered with cracks, and the latter sword body is covered with water ripples. This kind of cracked water ripple, laymen often think that it is a pattern engraved on the knife, but in fact it is a natural pattern formed after a hundred refinements. This kind of patterned blade, the blade is extremely tough and sharp, the edge is hidden in the serration, and because of the different combinations of steel and raw wrought iron, it has the characteristics of rigidity and softness, and other kinds of swords collide with it, and there is rarely continuous damage, which is the main reason why the patterned blade is better than the general sword. However, it is the same patterned blade, and the process is different due to the different quality of the metal. Yue Wang Goujian sword, the sword body uses tin copper smelting and casting technology, the pattern is formed by copper sulfide, and contains a small amount of aluminum and nickel. According to Cao Zhi's "Treasure Knife Fu" cloud: In Jian'an, Cao Cao ordered Yousi to make five treasure knives, which were known as dragons, tigers, bears, horses, and birds. According to Cao Pi's "Qu Theory", when Pi was the crown prince, he ordered his fellow workers to refine three swords, three swords, two daggers and one Lu Mo knife, all of which were named because of their posture: the sword "color like a rainbow" is called "Liucai"; the sword "like a spirit turtle" is called "Lingbao", the "color like Danlu" is called "Hanzhang", and the pattern of Lu Mo knife is called "dragon scale". Later, Fu Xuan's "Huidu Fu" of the Western Jin Dynasty also talked about the steel sword with patterns, saying that "the collar of Miao Mountain is cast as a sword; Shen Kuo's "Dream Creek Writings" said: "The ancient sword has the name of Zhanlu and fish intestines, and Zhanlu is said to be its color and black...... The fish intestine is the page of the steel sword of today, also known as the pine text: take the fish cooked, see its intestines, and now the steel sword text is also". The pattern of the steel sword is like a coiled fish intestine, and it is like a planed pine grain. The Central Plains plane pattern blade and rough surface pattern blade, its blade pattern is like an enlarged hand fingerprint, arranged in an orderly manner, exquisite, and the two slopes from the ridge of the sword body to the blade are not flat, but with a convex concave with an approximate plane, under the action of light, generated, a series of light waves of highlight points, the light waves flow in the opposite direction with the swing of the sword, which is dazzling. In this way, in practice, the opponent will regard the sword as a sword, and the sword as a sword, and the use of light is so ingenious, it really lives up to the martial soul for a thousand years, and China is absolutely invincible. In fact, how many people know how to know the pattern of ancient blades today, and how many people have seen it? Because the casting technology of pattern blades is extremely complex and difficult, and the makers are extremely secretive, only a few people have been fortunate enough to obtain them since ancient times, so they are extremely precious. In fact, the earliest patterned ancient blades came from the Central Plains. After Qin Shi Huang unified the six countries, he wanted to establish a foundation for all generations, so he implemented the policy of "selling troops and banning casting, burning books and pit Confucianism", and those experts who cast weapons fled to the four corners in order to avoid being killed, and those who fled to the east passed on their skills to Japan; those who fled to the northwest to pass on the skills of the Xiongnu, Turkic, Hui, and Dayue tribes; and leaked secrets to Persia in the south. Since then, the three famous knives of the outer fan have been produced. Persian Damascus patterned blades, Turkic welded patterned blades, Japanese dark-light patterned blades. The casting technology of the pattern blade, due to the difference between the region and the difference in the knife holder has formed its own style, take the three famous blades of the outer fan, for example, their common feature is that they have to go through iron smelting, sharp blades, quenching, sharpening, decoration and other processes, but the specific methods are very different, and the patterns also have their own characteristics: the pattern steel blade produced by the Turks, its veins are like silk weaving, and the luster is eye-catching; the pattern steel blade produced in Persia often has dozens of layers of cloud trapezoids, that is, the so-called Muhammad ladder, which is a strange and precious thing; and the pattern of the Japanese knife is rolled, and its veins are shaped like agate. The famous Damascus blade of Persia could easily cut through a few strands of silk thrown in the air. When the knife is cast, it is made with a special pattern called the Muhammad pattern, and the blade with this pattern is extremely jagged (indistinguishable by the naked eye), which makes the sword very sharp. The magical pattern on the Damascus steel knife is simply a symbol of sharpness and preciousness. Japanese swords use dark light pattern blades, which are divided into side flowers, belly flowers, small dark spots, and coarse dark spots. The bayonet consists of iron smelting, blade making, quenching and other processes. Iron smelting, the Japanese use their own steel, in the furnace leaves, smelting steel, pig iron, wrought iron and other different varieties. The steel cast in this way is sent to the knife worker, and it cannot be directly made into a blade, and it is also decarburized or carburized by a human furnace and melted into a strip. The blade maker heats the bar steel for hammer forging and folding it repeatedly to precipitate the debris from the raw material and make the steel symmetrical, and the pattern is also visible at this time. Quenching swords must be heated first, because the Japanese blade is a combination of steel with different properties, so the heating technology is extremely complex, and it is necessary to cover different textures of soil on different textures, and this soil-laying technology presents different patterns due to different schools. In the darkness of the night, the blade caster stared at the scorching fire, and when the blade burned to the required temperature, he quickly drew ten blades, removed the soil on the blade, and threw it into the water to vibrate several times, and after this quenching, the blade was hardened. After quenching, it is necessary to temper and then cool slowly, which can improve the toughness. After the sharpening of the sword is quenched, the blade is cut out by the smelter with a gravel, and the thickness of the blade is related to the needs of use. After the blade is opened, it is sharpened by a special grinder, and then the knife is equipped with a test handle for trial knives, and the decoration is done by a special sheath. With the gradual loss of the ancient sword casting technology in the Central Plains, the sword casting technology in the later period of the Central Plains was inferior to that of later countries. "Kunyi Road is far from being restored, and it is rumored that who can be poor when cutting jade. The sword is close to Japan, and the more Jia De's sea is east. The fish skin is attached to the fragrant wood sheath, and the yellow and white are mixed with copper. Hundreds of good people are good hands, and admiration can be inlaid with demons. This "Japanese Sword Song" confirms the influence of Japanese swords in the Central Plains at that time. According to Japanese history books, when Toyotomi Hideyoshi set out for Goryeo, the swords of the Goryeo samurai and the soldiers of the small kingdom were cut off by Japanese swords. Iron is refined into steel for a long time, steel is refined for a long time and is soft and pure, and then refined into green, and even more refined into treasure. Ordinary people only make iron knives and steel knives. The high-grade stainless steel knife, the steel color is pure, and it is calcined, and its texture is like a beautiful jade in steel. The stainless steel knife is refined into steel, and the iron is sharpened like clay, and the soft steel knife is soft and can be wrapped around the fingers. As for the green steel knife (iron iron) and treasure knife, it is a rare treasure in the world, and it is extremely difficult to obtain. Natural pattern steel was first produced in Persia. When smelting patterned steel, the Uzi is combined with a certain amount of dry wood, plant stems and leaves, etc. as a carburizing agent, placed in a crucible, sealed, and smelted at high temperature to obtain a block pattern steel. Then using the method of low-temperature forging, it can be made into a patterned steel blade, and the surface of the blade presents a black and white, thin curly pattern like a hair. This pattern is naturally formed when steel is smelted, and is the result of crystallization of the internal structure of steel, and its pattern shape is artificially uncontrollable, so it is called natural pattern steel. However, the raw material of pattern steel, Uzi steel, is produced in India. "A sword topaz can be talked about for so long, Xiao Zhaohua and the others heard it too much.
