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.
 
¡Ú1¡ÛUse of Dead Soft Iron
Use iron that has no impurities
¡Ú2¡ÛPreparing the Steel

The temperature in the picture is about (1000 - 1100¡î)
If the temperature at this time is too high, the steel will become unusable.
Hammer the steel to make it stronger.

¡Ú3¡ÛCompletion of the steel The steel is completed
¡Ú4¡ÛJoining Process Bury the iron into the hot steel.
¡Ú5¡ÛJoining Process Heat the iron (1000 - 1100¡î) and fold it into the steel.
The bonding agent is a mixture of boric acid, iron powder, and scrap iron.
¡Ú6¡ÛMelting

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¡î) 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.

¡Ú7¡ÛCompletion of the External Shape
Completion of the External Shape
¡Ú£¸¡ÛShaping¡Ê1¡Ë ·ÁÀ® This process is also very difficult.
¡Ú9¡ÛShaping¡Ê2¡Ë ·ÁÀ®2¡× It takes a person 10 years to be able to do this on their own.
¡Ú10¡ÛShaping¡Ê3¡Ë îí¤Î´°À® Forge and create the handle portion of the hatchet (nata).
¡Ú11¡ÛSurface Polishing 1 ɽÌÌ  
¡Ú12¡ÛSurface Polishing 2¡Ë ɽÌ̸¦Ëá2 Surface finishing (buffing)
¡Ú13¡ÛQuenching ¾ÆÆþ¤ì Quenching
This gives life to the blade.
How good or bad the knife will be is determined in this stage.
¡Ú14¡ÛAnnealing ¾ÆÌᤷ Annealing
This is to make all of the components of the blade uniform.
¡Ú15¡ÛStraightening Ïļè¤ê Remove any distortions in the straightness of the blade.
¡Ú16¡ÛSharpen the edge of the knife with a water whetstone ¿ÏÀè¤ò¿å¤ÈÀÐ Give an edge to the blade with a water whetstone.
¡Ú17¡ÛFinal Finishing ºÇ½ª»Å¾å¤² Polish the surface (final process)
Wash the blade in thinner, apply varnish, and attach handle.
