Swing your handbag at the attacker’s Adam’s apple, eyes, ears, or nose. If he’s able to grab it, though, let go; you don’t want him to use it to pull you closer, when the purse may be all he wants.
Use your heel—where nine times your body weight is concentrated—to stomp on your attacker’s foot. If you’re not close enough to stomp, heel-kick your attacker’s knee.
If you’re attacked from behind, throw your arm back and try to smash your watch face into the assailant’s nose. Rings on your fingers can do damage, too.
