Defender Ring vs. Pocket Knives

Pocket knives are one of the most common self defense products for women.  They're cheap, easy to use, and can be effective.  But what are the downsides?  Should a woman purchase a pocket knife with the intent of using it as her primary self-defense weapon?  In this article we'll discuss the various pros and cons of using pocket knives and how they compare to the Defender Ring™.

Pocket Knife Pros

A pocket knife is exactly as it sounds - a knife that's contained within an apparatus so that you can keep it in your pocket.  Pocket knives have many benefits associated with choosing one as your go-to self defense weapon.


Pocket knives are cheap.  You can purchase one online or from a local hardware store for $7-15 dollars.  Compared to Defender Ring™ which is $99 dollars, pocket knives are a more economical solution for women seeking personal protection on a budget. 

While Defender Ring™ is more expensive than a pocket knife, it's not just a self defense product, it's also a piece of jewelry.  The difference in cost is due to it being a fashionable jewelry accessory that women can wear everyday for aesthetic purposes.

Pocket knives can be very effective for self-defense purposes.  If you're able to accurately strike an attacker with your pocket knife, it can cause severe damage and even be lethal.  Pocket knives can be more effective than Defender Ring™ at defending oneself.  A pocket knife is a longer, bigger version of the Defender Ring™ blade weapon. 

While Defender Ring™ is not as big as a pocket knife, it's also capable of piercing skin, striking blood vessels and drawing blood, and hitting nerve endings and causing pain.  See our diagram which compares the Defender Ring™ blade weapon to human skin layers here: Blade Weapon vs. Skin Layers Diagram

Pocket Knife Cons

There are many cons to choosing a pocket knife as your go-to protective weapon.  What are the knife laws in your country or state?  A pocket knife may get you arrested in certain jurisdictions.  A pocket knife may be the best self-defense weapon on the market, but if it's hidden at the bottom of your bag when you need it most, that won't matter.


While knife laws vary from state to state in the U.S. and from country to country throughout the world, pocket knives generally fall under the category of being illegal.  This is because according to many laws, there is normally no other intent to carry a pocket knife, except to use it in a certain manner, which is in an illegal manner.  According to many laws, the primary purpose of a pocket knife is generally to cut or stab someone whether that's for offensive or defensive purposes. 

On the other hand, Defender Ring's™ primary function is a piece of jewelry.  The main intent of wearing the ring is for style and fashion.  However, always consult with a lawyer familiar with your local knife laws before making a purchase.

Illegal Pocket Knife


Pocket knives are not practical for women to carry in their bags every day.  Pocket knives can be heavy since they're made of metal.  They can be bulky and big depending on the blade length and knife style.  Carrying a pocket knife in a woman's bag everyday is an unnecessary item that she may never have to use.  Defender Ring™ on the other hand is a very practical self defense weapon.  It's small, light, inconspicuous and can be worn everyday as a regular piece of jewelry.


If you're walking down the street at night and a man appears out of nowhere and aggressively approaches you, how much time do you have to get your pocket knife?  Not a lot of time.  A random, unpredictable attack can occur in just seconds.  By the time you realize what's happening and start to unzip your bag to retrieve the knife, the attacker may already be on you.  Pocket knifes, or any defensive weapon that you have to carry in your bag, are not going to be accessible in a self-defence situation.

Defender Ring™ is unique since you always have it on your hand and therefore it's always accessible.  You never have to fumble around or search in your bag.  After wearing the ring regularly, you'll also be able to unscrew the ring top to unsheathe the blade weapon without even looking at it.

Self-Defense Weapon Features

A pocket knife has a great self-defense weapon feature in its sharp, long blade.  However, one feature it lacks is something to mount it to your hand.  A pocket knife can be knocked out of a victim's hand during a struggle, or used against her.  Defender Ring™ counters this by mounting the weapon on the woman's hand via the ring band.  It would be nearly impossible to knock Defender Ring™ out of a victim's hand in a struggle and use it against her.


Having any self-defense weapon is better than having none at all.  Pocket knives have their pros and cons.  Overall, while a pocket knife is inexpensive and can be effective, it lacks many features that make it a useful self defense product.  The fact that it's not practical to carry everyday, not immediately accessible, and generally illegal, make it a product that most women should stay away from as their primary source of personal protection.
