In the movie Kill Bill, multiple swords were used depending on the specific scenes and characters involved. The primary sword used by Uma Thurman's character, Beatrix Kiddo (The Bride), is a custom-made sword referred to as the "Hattori Hanzo sword."

The Hattori Hanzo sword is a fictional creation for the film, designed specifically for The Bride's character. It is a highly revered and exceptional weapon within the movie's storyline, crafted by the fictional legendary swordsmith Hattori Hanzo. The sword is depicted as a high-quality katana with intricate detailing, superior craftsmanship, and exceptional sharpness.

It's important to note that the Hattori Hanzo sword, as portrayed in Kill Bill, does not represent an actual historical sword or a sword produced by a real-life swordsmith named Hattori Hanzo. The sword is a fictional creation for the purposes of the movie's storytelling and adds to the overall narrative and visual style of the film.

Other characters in the movie also use various swords, such as the Crazy 88 members, who wield traditional Japanese katana swords, and O-Ren Ishii, who uses a sword inspired by the Japanese nodachi, a larger and longer variant of the katana.
