Katana sword was first produced over 1,000 years ago, and has remained one of the most revered weapons in history. Its design embodies the duality of conflict and peace, violence and serenity. It is designed to be lethal yet beautiful, and its forging technique aims to achieve three highly sought qualities, “not to break or bend,” as well as an ultra-sharp cutting edge. Swordsmiths often engage in purification rites before their work, and each hammer stroke is accompanied by fervent prayers. This transforms swordmaking into a spiritual journey – a journey of self-discovery and enlightenment.
To make a katana, the swordsmith needs high-carbon steel known as tamahagane. Iron sand is heated in a clay furnace to generate raw steel, which is then hammered and folded repeatedly to remove impurities and form the blade’s layered impression. After the initial shaping of the steel, the swordsmith heats and quenches it in water to harden it. This process allows the blade to be hard on its edges and softer on its spine, which gives it its signature curve.
After the hardening, the smith strikes and elongates the body of the sword to reduce its thickness, then creates the Kissaki (piercing tip). Finally, the smith uses files and planes to bring out the final shape. A katana should be carefully maintained and kept dry to prevent rusting. It should be stored in a clean, cool environment and not left in a sheath for prolonged periods of time, as this can trap moisture and lead to irreversible damage. buy a katana here
