How to make Shinken by Swords-smith
Material Iron
Japanese swords are made primarily of two different irons, known as "Tamahagane" and "Hochotetsu". Tamahagane is the strongest iron but it is also very rare, Hochotetsu which is more readily available, is generally used for items where durability isn't as crucial, like a kitchen knife. These ores are both extracted from iron sand which is found mainly high in the mountains. With special equipment called a "Tatara" using as little heat as possible and a great deal of time the iron is finally extracted. Even after this lengthy process, only a small amount of Tamahagane, is extracted so Tamahagane can be very expensive. Tamahagane is so rare and costly that it is normally added by "Oroshigane". By creating an alloy of different metals of varying density, most commonly a mixture of Tamahagane and Hochotetsu, the cost of producing a katana is much lower without sacrificing quality.

Structure of Katana
Japanese katana is made of two different hardness irons, the outside is the hardest iron containing Tamahagane, which is called "Hitetsu", and the inside is called "Shintetsu" used less hard iron. And using two different irons, soft inside and hard outside, makes Japanese swords "hard but unbreakable".


Process for making Katana
Heat the Tamahagane and Oroshigane with very hot fire to forge it.
Strike and stretch it with a hammer and fold it into two. It requires high technique because when you fold the iron, you must not put air in between. Continue those works many times to make the iron harder and purer. When you fold the iron ten times, the layers will be 1024. Then, forge the iron for Shintetsu by the same process as the Tamahagane.

Attach the Shintetsu and the Hitetsu.
And strike it with a hammer to make the shape of Katana.

Put "Hamon" on the Katana with a spatula.

Heat the Katana with very hot fire.

Cool the Katana by putting it into cold water.

Sharpen the Katana.
This work is called "Togi", and done by the specialist of Togi.
It takes one month. At this stage, the katana becomes very sharp.

To make 100% real Japanese sword very sharp and strong, it has to go through all this process
