TACHI
A tachi was a type of traditionally made Japanese sword worn by the samurai class of feudal Japan. The tachi style of swords preceded the development of the katana. An authentic tachi averages 70–80 centimeters (27 9/16 - 31 1/2 inches) in cutting edge length (nagasa) and compared to a katana was generally lighter in weight in proportion to its length, had a greater taper from hilt to point, was more curved with a smaller point area. Unlike the traditional manner of wearing the katana, the tachi was worn hung from the belt with the cutting-edge down, and was most effective when used by cavalry. For a sword to be worn in "tachi style" it needed to be mounted in a tachi koshirae. The tachi koshirae had two hangers (ashi) which allowed the sword to be worn in a horizontal position with the cutting edge down.

The blade of this sword is made of T10 carbon steel. 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.
