Japanese sword should be called the representative of the traditional technology in Japan, is made by the sum steel as a raw material iron sand, the sharpness is famous all over the world.
Steel Hitachi Metals Co., Ltd. has developed from a raw material for the steel sum is Yasukihagane.

I started building steel Hitachi Metals Co., Ltd. is founded Yasugi factory carry on the tradition that has been refined to the ball steel "Tatara process" from iron sand high purity that can be taken in the Chugoku Mountains once.


, White steel
All of the material of the steel is the raw material of iron sand system of good quality. Sharp blade with a grinding stone in, white steel, was considered to be the greatest thing since sliced ​​bread in particular.

Temperature zone the effect of quenching exiting on narrow blank of purity, not a complete quenching If you do not quench from optimal temperature, hardness does not appear.

Skill of the smith is questioned, let's say steel arm tremble much. 600 years of skill and traditions Sakai has Zui live here. Please be assured. Luxury kitchen knife of our store are made by craftsmen of reliable technology. I do not do the job, such as dirty in the name of "Sakai" never.



-Forging processes and forging
By hitting it with a hammer by heating red square timber of soft iron, sprinkled with iron oxide powder and borax as an adhesive, and put a small piece of steel, and then heated at a temperature range of 900 ° C in. When you hit it with a hammer, the coating of iron oxide also pop out borax that melted at the same time that pops out, skin and new skin of steel and soft iron is pressed. The mixture was heated in a furnace, and extend the core and tip, and we are in the shape of a kitchen knife approximate.

After you thoroughly dried, heated to 780 ° C in a furnace, and it comes to an appropriate temperature part of the steel was on fire, and then quenched in water is taken out.

• The tempering
Part of steel finished quenching has been hard, but it is very brittle. Was placed in a furnace temperature of about 150 to 200 ° C again, it is cooled slowly with water. It is a process to issue a tenacity to cutlery. With the exception of the soil and he says, You can correct that by hitting it with a hammer and strain bending of the kitchen knife.

And polishing
In place of the fine grinding wheel gradually from rough grinding stone eyes, while flowing the cooling water of a large amount, we will begin to sharpen the blade. I will finish the haze of luxury specification to clarify the boundaries of the steel.
