There are 3 instinctive defensive moves that you can use to defend yourself while wearing a self defense ring.

1. Punch
Wear your self defense ring, make a fist, and punch an attacker in the eyes, throat or face to create a deep puncture wound.

2. Slash
Wear your self defense ring, make a fist, and slash an attacker using a sideways motion in the eyes, throat or face to create a long gash.

3. Grab and Pull
Wear your self defense ring on the inside of your palm so the knife is facing inward instead of outward. Grab an attacker's arm and pull to gouge and create a long gash.
