Self Defense Rings for Women

Self Defense Rings for Women

Trendy, small, and inconspicuous. Defender Rings™ are wearable self-defense jewelry rings for moms, young professionals, joggers, and everyone in between. Presenting the most practical, dual-purposed self-defense weapon for the modern day woman that can be worn as a regular everyday ring. The ring can be transformed into a blade knife used for personal protection in under 1 second.




    Choose from seven (7) interchangeable, stylish designs that can be worn regularly as a fashion accessory. Our self-defense ring is the first true dual-purposed product to be worn as everyday jewelry.


    The Defender Ring™ self-defense product is equipped with a protective 5 mm double-sided curved blade with pointed tip. Use the blade weapon to defend yourself in a dangerous situation against an attacker.


    Transform your stylish everyday ring into a sharp personal protection blade by unscrewing the ring top. As long as you wear the ring as an accessory, you'll always have the self-defense weapon handy.


    Joggers and runners can wear the Defender Ring™ as a fashion accessory. You won't have to wear ugly, weird self-defense rings or carry a small can of pepper spray on your key chain. In the presence of danger your chic jewelry can transform into a self defence blade in under 1 second.


    Wear the Defender Ring™ daily whether you're going to work, running errands, eating dinner with friends, or out for a jog. The ring blends into your attire and looks like a normal everyday piece of jewelry. It's small, light, fits comfortably on your finger, and can present different looks with our rotating designs.


    Most weapons can be knocked out of a victim's hand in a struggle. It's nearly impossible to knock the Defender Ring™ out of a victim's hand since it's mounted on the wearer's body. Simply make a fist to securely mount the weapon to your hand and prevent it from being knocked off.

How big and sharp is the blade?

The blade is 5 mm in length by 3 mm in width at the base, with a spine of 1 mm. It's a double-sided curved blade with razor-sharp edges and a pointed tip. Click here to read our in-depth article about the top defensive blade properties.

What is the Defender Ring™ made of?

The Defender Ring™ is made of stainless steel.

How does it work? How do I unsheathe the self-defense blade?

The user can simply wear the Defender Ring™ like any other ring piece of jewelry on her finger. In the presence of danger, the user can remove the ring top by unscrewing it in a counter-clockwise direction using her other hand in order to unsheathe the self-defense blade.

The blade looks small. How will it deter or disable an attacker?

The blade is extremely sharp and measures 5 mm in length by 3 mm in width at the base. For comparison, the outer most layer of skin on humans known as the Epidermis is on average 1 mm thick and 20% of the length of the blade. The layer beneath it known as the Dermis contains both the blood vessels and nerves, and is on average 2 mm thick, which is 40% of the length of the blade. In a self-defense situation, the victim could strike the attacker wearing the Defender Ring™, draw blood, hit nerves, and still only have used 50% of the blade. Furthermore, if the user struck the attacker with the entire 5 mm length of blade, the blade can potentially hit muscles and bones of the body.

Is the Defender Ring™ legal to own and wear?

Please consult with an attorney regarding the legality of purchasing this product. Self-defense weapon laws vary from state to state and Defender Ring™ does not make any claims to the legality of this product. However, this product is intended to be used primarily as an ornamental ring piece of jewelry.

Can both women and men wear the Defender Ring™?

Yes, of course both men and women can purchase, wear, and use the Defender Ring™. The Defender Ring™ has been developed as a self-defense product for women, but our wide range of ring sizing options allows for both women and men to purchase and wear the ring comfortably.

Does the Defender Ring™ require any maintenance?

The Defender Ring™ requires minimal maintenance. As both a piece of jewelry and a blade, the Defender Ring™ must be intermittently cleaned and cared for to maintain its appearance.

Why is the Defender Ring™ better than a pocket knife?

All self-defense products have different advantages and disadvantages. We believe that carrying a bulky pocket knife in your bag is inconvenient and impractical, as well as threatening and possibly illegal. That's why we developed the Defender Ring™, so women can wear it regularly just as a piece of jewelry that doesn't need to be carried in your bag. Click here to read a longer post comparing the advantages and disadvantages of the Defender Ring™ vs. pocket knives.

Why is the Defender Ring™ better than pepper spray or stun guns?

The Defender Ring™ is very different from both a stun gun and pepper spray. While all three self-defense weapons are effective and can deter or disable an attacker, only the Defender Ring™ is immediately accessible and can be worn on your finger every day. Stun guns and pepper spray are bulky and must be carried in your bag, and retrieved from your bag in the presence of danger. We've written a detailed article comparing the Defender Ring™ vs. pepper spray self-defense weapons and stun guns here.

Why is the Defender Ring™ better than taking a self-defense or martial arts class?

Self-defense classes are a very special art that requires years of practice, patience, dedication, and skill. It's hard to compare the Defender Ring™ to taking self-defense classes as they are very different. In some respects, you can look at the Defender Ring™ as an effective quick fix to this problem, and self-defense classes as a long term solution. The best option would be to combine the two together, as self-defense classes utilize many finger, hand, fist, and arm motions, that when combined with the Defender Ring™ can be extremely effective.
