The traditional craftsmanship of Loulan Treasure Knife

A brief introduction to the Loulan Treasure Knife:

1. Pure steel (steel) is the mother of the craft system: the best steel knife, steel color is pure, purely hand-calcined, the texture is like steel in the jade (non-machine-polished). Knife quality classification: iron knife, steel knife, pure steel knife (steel), soft steel knife, green steel knife (hand-forged patterned steel), treasure knife (wootz\meteorite iron knife, political steel, casting type crystallized patterned steel). Iron is refined into steel for a long time, steel is refined into soft and pure for a long time, then into green, and even more into treasure. The average person will only build iron knives and steel knives. Top quality steel knife, steel color is pure, calcined, its texture is like steel in the jade; soft steel knife, soft can be wrapped around the finger. As for the green steel knives and treasure knives, they were rare treasures in the world and extremely difficult to obtain.

2. Wolf bite edge: the process is very special, different from the usual common wrapped steel and clip steel technology.

3. Spin welding: that is, the ancient political sword technology, the process is pure, secret circulation, usually secret.

Second, the unique process of the Loulan sword

Double-liquid quenching method, water quenching can increase the hardness of the blade, oil quenching can increase the toughness of the use of oil and water quenching method of double-liquid quenching method can be the best of both worlds, to achieve the effect of steel and soft. Only one quenching medium, after all, it is difficult to get the best of both worlds, double quenching method is a complex quenching process, mastery is not easy. Hundred refining steel technology is not completely folded forging, does not mean that the package steel, folder steel, should be referred to spin welding, can achieve the effect of rigid and flexible, sharp and incomparable, due to the use of secret heat treatment, the internal role of the formation of steel crystals, the edge of its hidden tiny serrated teeth. Low-temperature cold forging method: belongs to the extremely fine sword craft, reduces carbon loss and improves the quality grade. 1. Sharpening iron like mud and blowing hair off hair are only skillful performances, and have nothing to do with the variety of the sword (it is related to the thickness of the edge and the torque of the blade's width and thickness). At the same time, it is much easier to perform blowing hair and cutting iron like mud, the blade must be wide, the thickness of the upper and lower edges are different. Knife cut iron nails, is also very easy to do, the trick is in the hard stone of the nails.

2. Durability without steel fire: the knife is still sharp after a long time of use. But when it comes to sharpening, the more resistant a knife is to wear, the harder it is to sharpen. No matter what material, no matter how hard it is, it will be blunt after use. The choice of the degree of wear resistance depends on the level of forging and heat treatment, also known as steel fire. Steel fire good knife, edge damage, the more sharpened the sharper.

3. Steel and flexibility: the back of the knife and blade hardness is different, so do not think that the hardness of the back of the knife is the hardness of the edge, because if the entire body of the knife are used in high hardness steel, in the process of harsh use of the knife body may be damaged. The back and the edge actually play different roles and thus require different properties. The edge of the blade requires a relatively high degree of hardness, so it should be manufactured from a steel with a higher carbon content and greater hardness. The back of the knife mainly plays a supporting role, requires a better toughness, so that the knife is not broken when subjected to a relatively large impact, so we must choose a lower carbon content, toughness of the material.
