"A katana is a type of Japanase sword and is often called a "samurai sword." The term katana may be applied to any curved Japanese sword with a blade length of greater than 60 cm (23.6 inches). The term is sometimes incorrectly used as a generic name for any kind of Japanase sword

The katana is characterized by its distinctive appearance: a curved, slender, single edged blade, circular or squared guard, and long grip to accommodate two hands. It has historically been associated with the Samurai of feudal Japan, and has become renowned for its extraordinary sharpness and cutting ability, to the point that its purported cutting capabilities have reached mythical status."
