Katana Steel blocks beat
Knife workers will be burning red steel pieces forging, steel pieces hammer opened and then folded up and beat, so repeated, chase the 10th, there will be 1024 layers of steel, through this step, the steel can be sulfur and other impurities And excess carbon and other clear, to increase the elasticity and toughness of steel. This is like kneading in general, the more layers of the beat, steel and carbon in a variety of ingredients will be more uniform, iron crystal will be more detailed, and ultimately forging out the quality of steel uniform, up to thousands of layers, very tough The
Japanese knife shape regardless of the tip or the whole blade is a round-based shape, the reason why the blade is mainly composed of steel and quenching caused by the quenching. First of all, the knife to the carbon content of the hard and more hard blade gold (Hagane, Hagane), leather iron (Kawga gok, Kawagane), will be less carbon content and soft heart (Shinguan), Shingane, It is a major feature of Japanese knives, such as the double construction of Japanese, which is called Japanese (つ く り こ み, Tsukurikomi). The outer edge of the gold and the leather makes the knife sharp and has the proper hardness not to bend. The subsequent firing stage controls the difference in the volume expansion of the tip and the other portions in terms of the amount of carbon and the rate of chaking. So that the tip produces a strong compressive stress makes the sword more vulnerable to damage, and the formation of machetes arc. After the Song Dynasty, the Japanese sword knife more and more appear in China, the Chinese society had a wide range of influence, to the peak of the Ming Dynasty.
