The kubotan is a great self defense tool for everyday carry. It's made of solid and durable material, designed to fit comfortably in your hand, and is perfect for attaching to your car keys, purse or bag or carrying in your vehicle. It can be used to gouge an attacker's eyes, press into the bones of the hand, shoulder, or neck for self defense, and can also be used as a window breaker in an emergency (aim for the corners- particulary the bottom left or bottom right). Comes in a variety of matte colors.
