Katanas are traditional Japanese swords known for their distinctive curved, single-edged blade and intricate craftsmanship. They have been used by the samurai class in Japan for centuries, symbolizing honor and martial skill. The design of a katana allows for swift, precise cuts, making it a favored weapon in various martial arts, including Kendo. The making of a katana involves a meticulous process that includes folding the steel multiple times to create a strong and resilient blade. Each katana is unique, often featuring beautiful engravings and a handle wrapped in tsuka-ito. Today, katanas are not only weapons but also cherished collectibles and works of art.
