Stage combat swords, also known as theatrical or performance swords, are specially designed swords used in stage productions, film, and other performance contexts to create the illusion of combat while ensuring the safety of the performers. These swords are distinct from real weapons and are engineered with specific features to minimize the risk of injury during fight sequences. Here are some key characteristics of stage combat swords:

1. Blunted or Rounded Tips: Stage combat swords typically have blunted or rounded tips instead of sharp points found on real weapons. This reduces the risk of accidental puncture or injury when performing close-quarters combat.
2. Blunted Edges: The edges of stage combat swords are often dulled or rounded to prevent accidental cutting or slashing injuries. However, they still retain enough shape and definition to maintain the appearance of a real sword from a distance.
3. Flexible Blades: Stage combat swords often feature flexible blades made of materials like spring steel or carbon steel. The flexibility allows the sword to absorb and distribute force more evenly, reducing the risk of injuries caused by excessive impact.
4. Reinforced Tips and Blades: To enhance durability and safety, stage combat swords may have reinforced tips and blades. This reinforcement helps prevent bending or breaking during intense combat sequences.
5. Hilt and Grip Design: The hilt and grip of stage combat swords are designed with safety and comfort in mind. They may incorporate features such as rounded or padded guards and ergonomic handle shapes to provide a secure grip and minimize the risk of accidental hand injuries.
6. Weight and Balance: Stage combat swords are often weighted and balanced to feel similar to real weapons, allowing performers to execute choreography more convincingly. However, they are typically lighter than their authentic counterparts to reduce strain on the performers and facilitate precise movements.
7. Visibility and Audibility: Stage combat swords are designed to be visible and audible to the audience. They may have distinctive shapes, sizes, or colors that make them easily distinguishable from real weapons. Additionally, they may produce a sound when they make contact, created through the use of blade-to-blade contacts or sound effects.
8. Regular Inspection and Maintenance: Stage combat swords should undergo regular inspection and maintenance to ensure they remain safe for use. This includes checking for any signs of damage, wear, or loosening of components that could compromise their integrity.

It's important to note that the specific design and features of stage combat swords may vary based on the production's requirements, the type of combat being depicted, and the preferences of the fight choreographer and director. Safety protocols, training, and supervision are vital when working with stage combat swords to ensure the well-being of the performers involved.
