Dermis, the next layer, is 2-3 mm deep and contains blood vessels and nerve endings. Our Minimalist Rings can fully penetrate the Dermis layer of skin with 60-80% of its blade length.

Our Maximalist Rings have a larger blade weapon and can devastatingly cut through human skin, draw blood, and inflict damage.

Our concealed self defense rings can be unscrewed in approximately 2-3 seconds. With practice, most people can unscrew them in less than 2-3 seconds.

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.

1. Inflict Serious Pain to an Attacker

All of our self defense rings have blade weapons that can strike nerve cells and inflict serious pain to an attacker.
