The clay temper procedure is really complicated,although what we show you is only four steps.The blade will be set apart as 2,one is the back of the blade and the other is the cut edge side.the back side will be stick with the clay and the other side will be covered by the powder and other mixture which is protected as a secret recipe.coz the different thickness of the back of the blade and the cut edge side,and the different of the clay mud and the mixture,when the blade cooling to be a same low temperature at the same time after the heating by high temperature,that is why the blade has a radian,and there is a clay temper wave line.


Kobuse

In addition to folding the steel, high quality Japanese swords are also composed of various distinct sections of different types of steel. This manufacturing technique uses different types of steel in different parts of the sword to accentuate the desired characteristics in various parts of the sword beyond the level offered by differential heat treatment.

The vast majority of modern katana and wakizashi are the maru type (sometimes also called muku) 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). Honsanmai and shihozume types add the third steel, called kawagane (skin steel).There are almost an infinite number of ways the steel could be assembled, which often varied considerably from smith to smith. Sometimes the edge-steel is "drawn out" (hammered into a bar), bent into a 'U' shaped trough, and the very soft core steel is inserted into the harder piece. Then they are forge welded together and hammered into the basic shape of the sword. By the end of the process, the two pieces of steel are fused together, but retain their differences in hardenability.
