Self-defense batons are compact, portable, and effective tools for personal protection. Here are some popular types of batons for self-defense:

1. Expandable baton: Also known as a telescopic or collapsible baton, this type of baton can be easily carried in a pocket or bag and extended to its full length for use in self-defense situations.

2. Steel baton: Made of solid steel, these batons are durable and provide a strong impact when used for self-defense. They are typically heavier and more rigid than expandable batons.

3. Rubber baton: Rubber batons are lightweight and flexible, making them ideal for striking an attacker without causing serious injury. They are also less likely to cause permanent damage compared to steel batons.

4. Tactical baton: Tactical batons are designed for law enforcement and military use, featuring additional features such as a textured grip, flashlight attachment, or window breaker.

When choosing a self-defense baton, consider factors such as size, weight, material, and legality in your area. It’s also important to practice using the baton safely and effectively to protect yourself in a threatening situation.
