In the production of "The Lord of the Rings" film trilogy directed by Peter Jackson, a combination of real swords and prop swords was used. The choice of using real swords versus prop swords depended on the specific requirements of the scenes and the safety considerations of the actors.

Real swords, typically made of steel, were used for some close-up shots and certain combat sequences where the actors could handle them safely. These real swords were often modified and blunted to minimize the risk of injury during fight scenes.

However, for more intense or high-action fight scenes, as well as scenes involving stunts or intricate choreography, prop swords made of materials such as lightweight aluminum or rubber were used. These prop swords are designed to be safer, easier to maneuver, and minimize the risk of accidental injury to the actors.

Safety precautions and rehearsals were paramount in the production to ensure the well-being of the actors and the overall success of the fight scenes. Stunt coordinators and trained professionals supervised the swordplay, and careful attention was paid to choreography, blocking, and controlled movements.

Ultimately, the goal was to create realistic and visually engaging sword-fighting sequences while prioritizing the safety and well-being of the cast and crew.
