Other Color:Click Here Ancient quenching: Modern vacuum heat treatment can meet the hardness requirements of most swords, but the traditional quenching method has better effect, can soften the medium strip steel, and the hardness is higher. Dao： Dao are single-edged Chinese swords, primarily used for slashing and chopping. The most common form is also known as the Chinese sabre, although those with wider blades are sometimes referred to as Chinese broadswords. Manual grinding: Using the unique bright stone of Longquan Town, hand grinding, very test sword casting skills and technology, grinding out the pattern effect is special texture! Chinese Sword: Swords have a long history in China. Bronze swords have been traced back to the bronze daggers of the Shang dynasty. Bronze long swords suddenly appeared during the mid-third century BC. Later swords were made of iron or steel. These metals were wrought, never cast. Swords commonly reached a length of 70–100 cm, although longer swords have been found.Chinese iron swords were used in Japan from the third to sixth century AD, but were replaced with Korean and native Japanese swords by the middle of the Heian era. The Chinese classify all swords into two types, jian (剑) and dao (刀). Jians are dual-edged while daos are single-edged.

You need pay additional $20 for engraving patterns (dragon, lion, etc.) or other logos.HOW TO DISASSEMBLE A JP SWORDSWORD MAKING PROCESSESFormingSwords can be shaped by a variety of metalworking techniques.The primary techniques are forging and stock removal. Forging uses heat to bring the material to a malleable state. The material is then hammered to shape, typically using hammer and anvil together with specialized set and fuller tools depending on the particular technique. Stock removal shapes the sword from prepared stock that is larger in all dimensions than the finished sword by filing, grinding and cutting.QuenchingAfter 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. The more rapidly a blade cools down, the harder it becomes. Thus, when a hot blade enters the water, the water also gains heat and the blade will cool more gradually. Therefore, the first part of the blade that enters the water will be the hardest. Therefore, the technique of quenching was also very important. If a blade has any flaws from forging (air bubbles, ash), it will break immediately during the quenching process.Tempering After quenching, the sword will be quite tough and brittle, with little flexibility. To overcome this, the blade would undergo a tempering process. The blade would be reheated to a certain temperature degree then allowed to cool naturally. The blade would be slightly less tough afterward but have a greater degree of flexibility – the art would be to perfectly balance the blade for toughness, sharpness and flexibility. Modifying ShapeFinishing Finishing encompasses polishing, decorating, and crafting and assembling the hilt, guard and sheath. The swordsmith would be most concerned with the state of the blade itself and possibly decorating the blade and preparing the guards and pommel. Other artisans would likely be involved in the work of fashioning the hilt, sheath and other furniture; and in any fine decoration. PolishingWhen the rough blade is completed, the swordsmith turns the blade over to a polisher, whose job it is to refine the shape of a blade and improve its aesthetic value. The polishing process almost always takes longer than even crafting, and a good polish can greatly improve the beauty of a blade, while a bad one can ruin the best of blades. Early polishers used three types of stone, whereas a modern polisher generally uses seven.On high quality blades, only the back of the blade and the adjacent sides, are polished to a mirror-like surface. To bring out the grain and hamon, the center portion of the blade, and the edge are usually given a matte finish. Microscopic scratches in the surface vary, depending on hardness. Smaller but more numerous scratches in the harder areas reflect light differently from the deeper, longer scratches in the softer areas. The harder metal appears more matte than the softer, and the manner in which it scatters light is less affected by the direction of the lighting.After the blade is finished it is passed on to a mountings-maker for fashioning the hilt, sheath and other mountings.NOTICEInternational Buyers – Please Note:a) Import duties, taxes and charges are not included in the item price or shipping charges.
