KATANA | |
Historically, katana (刀 or かたな) were one of the traditionally made Japanese swords (nihontō) that were used by the samurai of ancient and feudal Japan.The katana is characterized by its distinctive appearance: a curved, single-edged blade with a circular or squared guard and long grip to accommodate two hands. Samurai katana as a weapon is famous for its beautiful shape. They are used as art collection and the symbol of samurai soul. Our sword allows you to make a collection or to send to friends as a present. |
The blade of this sword is made of damascus folded steel. It is folded forged by 15 times, and 32768 layers of patterns(Jihada) are formed on the surface of the blade. It is also clay tempered. The high-performance blade has very good toughness and does not deform when bent at 90 degrees. The hardness is as high as 60. Cutting the wire does not hurt the blade. It can be used in battle or for display. We would highly recommend it as a gift. Anyone would be thrilled to receive a gorgeous sword as a gift! |

CLAY TEMPERING | |
Before being quenched, a special clay mixture can be applied onto the blade to harden the edge and obtain different hardness on the blade. The clay mixture was a special recipe and considered a crucial trade secret, guarded protectively by sword making masters. It would contain such things as feathers, powdered bones, grass, etc. and would be applied to the edge of the blade before being quenched. During quenching, a chemical reaction between the clay mixture and the hot steel occurs during the sudden temperature drop and carbon is fed into the blade in high amounts, creating an extremely tough edge. A clay hardened blade can only be quenched in water, thus increasing the defect rate even more. Another way for clay tempering is to apply clay along the blade but let edge exposed. Thus, while quenching the blade into water,the uncovered edge will cool down suddenly, but the rest of blade will cool down slowly. Such differential temperature change results in the different hardness of the blade. So the edge is tough enough to cut, where the back of blade is soft /flexible enough to absorb the impact during cutting. Such quenching process usually will leave beautiful wavy tempered line on the blade, as known as "hamon" in Japanese swords term. | |
POLISHING PROCESS - SHIAGE TOGI | |
The polishing process is divided into two stages:Shitaji togi and Shiage togi.The polishing process almost always takes longer than even crafting. Shitaji togi is Foundation polishing,to correct any bends in the blade.Shiage togi is the stage that places the mirrorlike finish on a blade. This sword used Shiage togi,it is a elaborate process to the blade,it uses small grindstone to polish the blade by hand to make the blade mirrorlike,it is a time-consuming work,it can effectively increase the sword's monetary,historic,artistic,and functional value. |
