In the movie "Kill Bill," various types of swords are used during fight scenes and action sequences. While some swords used in the film may appear similar to traditional Japanese katana swords, it's important to note that they are primarily props specifically designed for the purposes of the film.

The swords used in "Kill Bill" were likely custom-made for the movie and crafted to meet the specific needs of the scenes, stunts, and choreography. These swords were likely made with the guidance of professional swordsmiths, prop makers, and stunt coordinators to ensure safety and functionality during filming.

It's important to remember that real swords, particularly sharp and functional ones, require proper training, expertise, and caution when handling. The swords used in movies are often modified and adapted for on-screen performance, which may involve altering the blade's sharpness, balance, or other characteristics to accommodate the demands of action sequences and ensure the safety of the cast and crew.

Therefore, while swords are depicted in "Kill Bill," the ones used are specifically made for the movie and may not necessarily reflect the characteristics or construction of authentic historical or functional swords.
