It is small and can fit into your pocket or purse easily. If you do not have that available use what ever hard object you can find to stop the attacker. A brush or even your purse makes an excellent weapon. If the man is trying to steal your purse, let him have it. There is nothing in your hand bag that is worth risking your life over. You need to know what techniques that will save you at the time of the attack. The seminar focuses on just those skills. The instruction is so fluid that you will be able to pick out the style that fits both your mind and your attitude. You do not have to be a black belt or a muscle woman to practice women's self defense. You are about to get into your car and a stranger walks up to you trying to get your attention. You are nervous but you don't want to be rude. You approach the stranger and at the same time he reaches out and tries to grab you. You have never been to a traditional women's self-defense course and you really do not know what to do. He lunges for you and grabs your hair. You now wished you have taken a women's self-defense course but now it is too late. You would not need a woman's self-defense course if you had a Taser. What is a Taser you ask? A Taser is a non-lethal weapon that uses compressed nitrogen to shoot out tethered needle probes that when applied can deliver an electric shock that will disable your assailant. The more panicked the whistle sounds the more attention it will get from a passerby. Run while you are blowing it. Try to get into your car or a building that is nearby. Do not be afraid to knock on a stranger's door or even enter it without permission if you are being chased. The charge of breaking and entering is worth it if it saves your life. Even if they were is it not worth the experience and the cost to take them. Remember there is only one of you on this earth and once your injured either physically or emotionally, there is no way to bring you back to the person that you are now. So take the time and find a class. Enroll and attend. Take another female friend or family member with you.
