About Our Rings

Answers to the most frequently asked questions about our rings:

What's the difference between your Minimalist Rings, Maximalist Rings, and Serrated Rings?

Our Minimalist Rings, Maximalist Rings, and Serrated Rings are all self defense rings with sharp concealed blades, designed as everyday jewelry.

Our line of Minimalist Rings is called Defender Ring and are equipped with a concealed 5 mm blade weapon.

Our line of Maximalist Rings is called Defender Ring X and are equipped with a concealed 10 mm blade weapon.

Our line of Serrated Rings is called Defender Ring Z and are equipped with a concealed 10 mm saw-tooth blade weapon.

How sharp is the weapon? What can it cut?

All of our rings have a sharp blade weapon with grinded edges and a pointed tip. They can cut through fabric, plastic and thin metal and can easily rip, tear and cut through human skin.

How deep can the weapon cut into skin?

Epidermis, the outer layer of skin on humans is on average 1 mm deep and equal to 20% of Defender Ring's blade length.

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

Defender Ring X and Defender Ring Z have a larger blade weapon and can devestatingly cut through human skin, draw blood, and inflict damage.

How long does it take to unscrew the ring tops?

All of our self defense rings can be unscrewed in approximately 2-3 seconds. With practice, most people can unscrew our rings in less than 2-3 seconds.

How do I defend myself with Defender Ring, Defender Ring X, and Defender Ring Z?

There are 3 instinctive defensive moves that you can use to defend yourself wearing our self defense rings.

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.

Defender Ring, Defender Ring X, and Defender Ring Z have blade weapons that can strike nerve cells and inflict serious pain to an attacker.

2. Cause Significant Damage to an Attacker
