Yes, the sword used by Uma Thurman's character, Beatrix Kiddo (The Bride), in the movie Kill Bill is a katana. A katana is a traditional Japanese sword characterized by its curved, single-edged blade, circular or squared guard (tsuba), and long grip (tsuka) that can accommodate two hands. The katana is a renowned weapon associated with the samurai warriors of feudal Japan.

In Kill Bill, the katana is prominently featured as the primary weapon of The Bride. The design of the sword in the film resembles a typical katana, with its curved blade, circular guard, and long handle. However, it's worth noting that movie props can sometimes deviate from precise historical or traditional specifications for creative or practical purposes.

While the Kill Bill sword may not adhere strictly to the exact details of a historical or traditional katana, it is visually inspired by the katana's iconic design. The sword used in the film serves as a symbolic representation of The Bride's martial prowess and plays a significant role in the action sequences throughout the movie.
