How the Katana Sword is Made


The Katana is the most famous sword in Japan, and one of the most desired weapons in the world. The blade is curved and often adorned with unique traditional patterns.

The katana was designed to be a weapon of choice for the Samurai, and as such it had to be both beautiful and functional. The curved shape allows the warrior to perform both slashing and thrusting moves with equal effectiveness, while also adjusting easily to an enemy’s wide movements. The curved form also provides the edge with an ability to cut deeper and more effectively than straight swords.

To create a high-quality Katana, the metal is first forged using a process called Tamahagane. This traditional steel is made from iron sand and charcoal in the clay Tatara furnace, which produces a mixture of hard and tough steel, creating an ideal blend of durability, strength, and a deadly cutting edge. The smith then hammers the tamahagane to remove all slag, creating a channel that is slightly smaller than the tough, low-carbon steel he will insert into it. The smith then forges the two metals together, creating a strong and flexible sword that will never break or bend in battle.

Once the tamahagane is complete, it is heated again in a charcoal fire for a process called Yaki-ire, which hardens the surface of the metal, creating Martensite. After this, the smith will sharpen the blade and add a Kissaki (piercing tip). To finish off the sword, he will drill a Mekugi hole to secure the Tsuka, wrap it in a samegawa or tsuba, and add menuki, which are tsuka ornaments. Samegawa is traditionally a natural material derived from the dried skin of a stingray, but it can also be synthetically produced. buy a katana here
