The Katana is a Japanese sword that was used by the samurai in combat. It is a long bladed sword that is typically between 30 and 60 centimeters in length. The katana is used as the weapon of choice in many martial arts, including aikido, iaido, kendo and ninjutsu. While katanas are still used in combat, most modern martial artists use blunt-edged iaito instead of sharp katanas to reduce the risk of injury.
The katana was developed in the Muromachi period, where many famous swordsmiths produced blades that are revered for their beauty and quality. The samurai of this period used their weapons for warfare and favored dynamic blades that were shorter, wider at the base and with a longer Kissaki (tip).
To achieve these qualities, the smiths of the time created a special type of steel known as Tamahagane, which was made using a forging method called the Tatara-buki method. This process combines iron and sand from Japan and uses a fast reduction method to create high-quality steel.
This technique allows the blade to be extremely hard with a sharp cutting edge, but also resilient and tough at its core. The resulting combination of qualities is best demonstrated by the distinctive wavy line or “hamon” that runs along the blade.
The katana’s other notable features include the tiara, koiguchi and menuki ornaments on its hilt. The tiara is used to prevent the blade from falling out of the wooden scabbard or koshirae, and it can be secured to the obi (sash) with a kaeshizuno hook. buy demon slayer katana online
