Yes, a samurai sword is typically referred to as a katana. The katana is a specific type of sword that was traditionally used by the samurai class in feudal Japan. It is one of the most recognizable and iconic weapons associated with the samurai.

The katana is characterized by its curved, single-edged blade, circular or squared guard (tsuba), and a long grip (tsuka) that can accommodate two hands. It typically has a blade length ranging from around 60 to 80 centimeters (24 to 31 inches).

The katana served as the primary weapon of the samurai and was prized for its cutting ability, balance, and versatility in combat. It was designed for powerful and effective slashing and cutting techniques, making it well-suited for close-quarters combat on the battlefield.

The katana also held cultural significance beyond its function as a weapon. It symbolized the samurai's social status, martial skills, and adherence to the code of bushido (the way of the warrior).

So, when referring to a samurai sword, the term "katana" is often used to specifically indicate the iconic curved sword associated with the samurai class in Japan.
