American customers can receive the packages 1-7 days after placing an order. 2 Because the item is already in the warehouse in the United States, we are sorry that we cannot add free carving service & replacement parts service for the moment. 3 We have free return service.If you don't like anything after you receive the package, we will bear the loss of return. We have our own sword-casting factory. The factory is located in Longquan, a small town with a long history of sword-casting in China. Most of the famous Swords in China are made there. Rich raw materials, skilled technology, traditional sword casting technology from generation to generation. Manual production really takes a lot of time. We hope to get your understanding.
Each handmade sword is unique. Our swords are great for gifts or for your own collection. Our swordsmithing master makes every sword attentively, hope you can feel our sincerity. After the blade has been shaped, the sword would be quenched.We quench our swords in either water or oil. Water quenching produces a tougher edge which can also be hardened further more using clay. Blades quenched in oil are still considerably hardened and do have superior flexibility compared to a water quenched blade. In the forging process, the most useful process is the folding, where the metals are forge welded, folded, and welded again, as many as 124 times(15 times is the best). The folding removes impurities and helps even out the carbon content, while the alternating layers combine hardness with ductility to greatly enhance the toughness. The less impurities, the harder and sharper the blade will be. We have done cutting tests on the blades. It can cut bamboo(young bamboo tree), grass mattings and slice paper(The blade should be tilted at 45 degrees). To maximize both the cutting edge and the resilience of the sword spine, a technique of differential heat-treatment is used. The sword is painted with layers of clay before heating, providing a thin layer or none at all on the edge of the sword, ensuring quick cooling to maximize the hardening for the edge. A thicker layer of clay is applied to the rest of the blade, causing slower cooling. This creates softer, more resilient steel, allowing the blade to absorb shock without breaking. The best quality of high carbon steel is at 1095, the carbon content was 1.03%, and the element contains a small amount of chromium, molybdenum, vanadium, after heat treatment can reach HRc58-60 hardness, toughness is very good, but not resistant to rust, more be applied to traditional european-style hunting knife, large cutting knife and military dao. Such as the United States during world war ii "KA - BAR" saber is in 1095 as the blade material. The vast majority of modern katana and wakizashi are the maru type which is the most basic, with the entire sword being composed of a single steel. The kobuse type is made using two steels, which are called hagane (edge steel) and shingane (core steel).
Steel of different materials is forged and welded together to hammer the basic shape of the sword. This allows the overall blade to have a higher toughness and absorb a lot of impact.Reducing the possibility of breaking or bending to some extent. Makes the blade not only has high hardness, but also has super toughness. A If you do not receive the package, or the package is damaged during transportation. We'll take care of it.
B If it is mentioned in the product description that the package includes the sword bag or sword holder, the style will be random. C If you have any problem after recieve the package wrong size, wrong style, etc. We always provide you with the best after-sales service. Please give us a chance to help you before you give us a bad feedback.
