Keep Your Keys In Your Hand and hold them between your fingers. Use them to jab at eyes, necks, throats or groins.
Be Observant and Aware of your surroundings and the individuals around you. Don't allow strangers into your personal space. Be alert, because distraction techniques are widely used by thieves.
Everything Is a Weapon... shoes, a purse, a watch, a pen, even a wedding ring. Don't be concerned about hurting any attacker, they don't care about you.
Fight Back; Fight Dirty! Someone once said, "If you're in a fair fight, you're doing it wrong." Fight fierce, fight hard!
