The term 'Single-Edged Samurai Sword' refers to a type of sword known as a katana, which is a curved, single-edged Japanese sword traditionally used by samurai warriors. The katana is characterized by its distinctive appearance: a curved blade with a single edge, a square or circular guard, and a long grip to accommodate two hands. It is considered to be one of the most iconic weapons in Japanese culture and is still used today in martial arts.
