Self-defense tools are items designed to help individuals protect themselves from potential threats or attacks. Common examples include pepper spray, personal alarms, and self-defense keychains. These tools are often compact and easy to carry, making them accessible for everyday use. Many self-defense tools are legal to carry, but regulations can vary by location. It's important for users to understand how to use these tools effectively and responsibly. Training in self-defense techniques, such as those taught in martial arts classes, can also enhance personal safety and confidence in dangerous situations.
