Think this is just a lovely piece of jewelry? Guess again. Normally, the Defender Ring looks as if it’s topped with a rose design. But if danger appears, you just have to remove the rose to reveal a small spike sharp enough to puncture.

David, Huffington Post

I found the Defender Ring to be a unique self-defense option for myself and would recommend it to other women. What I found likable about this self-defense product was that I could wear it 24/7 and it merely looks like a stylish piece of jewelry.

Sophie, Fitness Junkie

Since your self-defense tool needs to be in your hand at the time of an attack then why not consider a ring. It will always be in your hand and ready to strike. With a couple of quick twists, the crown of the ring is removed and then exposes a very sharp point.

Chad, Simple Self-Defense Blog

Unlike many other self defense rings we have tested, this one looks quite attractive and can be worn as a regular piece of jewelry. When you unscrew the rose ring top, you can use the sharp head to draw blood and collect DNA evidence.


Do I recommend the Defender Ring? Yes! It makes me more confident to work those nights shifts, or to go places on my own. This ring would be best with an accompanying self-defense class if you are not familiar with self-defense techniques.

Caitlin, HM Housewife

I was very impressed that it didn’t become unscrewed with daily wearing or while in and out of my pocket all day.  I was a little worried about that since I have granddaughters always playing with my jewelry or touching my hands.

Nancy, Things That Make People Go Aww

I poked my husband just gently with this, and he got a little mad at me for how bad it actually hurt him. It is that sharp! Defender ring can pierce skin, draw blood, and even collect DNA for police if you need to show it to them.

Amanda, Little Helpers

During an assault, the Defender Ring's deeper purpose is to go deeper.

Deeper enough to tear through human skin, slash at nerves and blood vessels, and maybe even cut to muscle and bone.

Dude I Want That

I don't know about you but I see so many stories out there of women literally being attacked. Not to mention being a sexual assault survivor myself. It teaches you to be more aware of your surroundings.

How big is the knife?

The knife is 5 mm in length by 2 mm in diameter. It's a quadruple-faced blade with thin grinded edges and a pointed tip.

How will the knife protect me if I'm attacked?

By wearing Defender Ring, the knife will be attached to your fist and provide extra power and cutting ability when you punch and strike. You'll be able to pierce skin, draw blood, collect DNA, and impair an attacker with your fist.

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 Defender Ring™, so women can wear it regularly as a piece of jewelry that doesn't need to be carried in your bag.

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

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 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, and retrieved from your bag in the presence of danger.

Why is 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 Defender Ring™ to taking self-defense classes as they are very different. In some respects, you can look at Defender Ring™ as an effective immediate solution, 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 Defender Ring™ can be extremely effective.

How do I wear different ring top designs?

All Defender Ring™ tops can be interchanged with one another and fit on all ring bands.
