There are secret techniques put into the forging process, and much time and effort is spent before a blade is finished. Now, let’s take a look at how blades are made.

【1】Use of Dead Soft Iron Use iron that has no impurities 【2】Preparing the Steel The temperature in the picture is about (1000 - 1100℃) If the temperature at this time is too high, the steel will become unusable. Hammer the steel to make it stronger. 【3】Completion of the steel The steel is completed 【4】Joining Process Bury the iron into the hot steel. 【5】Joining Process Heat the iron (1000 - 1100℃) and fold it into the steel. The bonding agent is a mixture of boric acid, iron powder, and scrap iron. 【6】Melting This is a very difficult process. It takes a person 10 years to be able to do this on their own. One hammers (1000 - 1100℃) metal in one go to joining the iron and steel together. It takes a minimum of 3 years to be able to do this process. 【7】Completion of the External Shape Completion of the External Shape 【８】Shaping（1） This process is also very difficult. 【9】Shaping（2） It takes a person 10 years to be able to do this on their own. 【10】Shaping（3） Forge and create the handle portion of the hatchet (nata). 【11】Surface Polishing 1   【12】Surface Polishing 2） Surface finishing (buffing) 【13】Quenching Quenching This gives life to the blade. How good or bad the knife will be is determined in this stage. 【14】Annealing Annealing This is to make all of the components of the blade uniform. 【15】Straightening Remove any distortions in the straightness of the blade. 【16】Sharpen the edge of the knife with a water whetstone Give an edge to the blade with a water whetstone. 【17】Final Finishing Polish the surface (final process) Wash the blade in thinner, apply varnish, and attach handle.
