Best Self-Defense Keychains: Pros and Cons

Thankfully, most people will never know what it’s like to fight for their life. But if you or someone you love has ever experienced an assault, home invasion, or other terrifying incident, you already know that the moment of attack is not when you want to be thinking about self-defense options for the very first time.


That’s where self-defense keychains come in. Successful self-defense is all about planning and preparation. If you invest in the right tool, you’ve already taken a big step toward ensuring your personal safety.


The best self-defense keychains don’t require a lot of training, and they can only be enhanced by it. These weapons go by tons of names, both branded (like Kubotan or MUNIO) and generic (like kubatons).


Keep reading to learn the pros and cons of the different types of self-defense keychains out there, so you can make sure you invest in the right one for your needs.



Kubaton Keychain














Also known as a kubaton in its genericized version, the Kubotan is a name-brand self-defense keychain that originated in the 1960s. Learn more about the Kubotan.


Pros

  • Effective against a variety of attacks, from both in front and behind

  • Can be used as a flail for striking at an extended range by whipping your keys

  • Can be used in joint lock and pressure point submissions (by those who are trained properly)

  • Safer around small children (depending on the design) compared to other leading self-defense tools

  • Generally considered non-lethal

Cons

  • As it was originally designed for use by law enforcement, training is often necessary to use the Kubotan to its fullest potential

  • Not legal in all states

  • May not be allowed in all public settings, such as sporting arenas or airplanes




Resin Self-Defense Keychain

Resin keychains are impact weapons made out of resin material oftentimes by DIY-ers.














Pros

  • Can be effective against a variety of attacks, depending on the mold used, quality of resin, skill of the maker, and shape

  • Can be personalized, customized, and made more aesthetically pleasing or unique

Cons

  • The edges may be sharp and therefore less convenient for everyday carry and less comfortable to hold, making it hard to handle or even unsafe if you actually need to use it

  • Questionable durability and longevity due to the weaker resin material

  • May not be allowed in public venues or legal in all states (depending on the shape and how it’s carried or used)




Pocket Knife Keychain














Pros

  • An exposed blade can scare off or stop an attacker

  • A blade may have versatile uses, such as cutting off a car seat-belt in an emergency

Cons

  • Generally, you need two hands to open it unless there’s a release mechanism

  • If there’s a release mechanism, there’s the possibility of mechanical failure

  • Depending on the size and shape, you may have limited range or less effectiveness against attacks from behind, such as the common bear hug

  • Due to its small size, you may not get good leverage with it on your keychain

  • May not be allowed in public venues like concerts, sporting events, etc.

As far as I see it, you’re better off buying a regular knife that has a better grip and a longer, more durable blade, which will make the knife more effective. Just be aware of the legal repercussions of carrying a lethal weapon.





Cat Self-Defense Keychain














The cat self-defense keychain is also known as the kitty cat self-defense keychain. Other similar items have different animals (like the dog version pictured here) or unique shapes as a primary part of its appeal — but consider if this is the most important aspect for you. If so, if there are other ways to satisfy your aesthetic taste without compromising your safety.


Pros

  • An effective tool for striking

  • Looks like a mean and nasty weapon, which can potentially scare off attackers

Cons

  • Impractical to use against the common bearhug attack from behind

  • Might be forbidden from public spaces like airplanes, concerts, sporting events, etc.

  • Illegal in several U.S. states, since its is gripped and used like brass knuckles

  • Can be difficult for larger hands to insert your fingers and hold comfortably




Personal Alarm Keychain

The main thing to know about a personal alarm keychain is that it’s supposed to scare the attacker away using noise. If that doesn’t work, you’ll still need to protect yourself.

Pros

  • The alarm sound might scare your attacker away

  • The alarm sound might attract attention and summon help


Cons

  • In some cases, the alarm sound is mistaken for a car alarm and people will not understand that you’re in immediate harm or that they should go for help

  • People may understand that you’re in trouble, but they may be too afraid or not inclined to help (unfortunately, many people are more likely to record an attack on their phone instead of jump in to help)

  • What if no one is around at all to hear the alarm go off?

  • Most personal alarm keychains require two hands to activate (top left image), because you have to pull out the top with one hand, while holding onto the bottom with your other hand. But, because an attack might limit your mobility, it’s best to look for those that are activated by pressing a single button with one hand (top right image)

  • This type of self-defense keychain is subject to mechanical failure

  • You have to make sure to keep the batteries charged



Self-Defense Keychain with Pepper Spray














It’s important to note that pepper spray, bear spray, and mace are not all the same substance and will be subject to different legal restrictions in different states.


Pros

  • Can effectively deter an attacker if applied right

Cons

  • Subject to environmental conditions (wind, rain, etc.)

  • Has a limited shelf life

  • Difficult to use against an attack from behind

  • Subject to mechanical failure

  • May not be allowed in public spaces, on airplanes, or among crowds

  • Not safe around small children




Stun Gun Keychain














Stun gun keychains are often called “taser keychains” — but they’re not the same thing at all. Tasers are gun-shaped weapons that shoot out a wire that attaches to your attacker with sharp prongs and delivers a shock via the wire. I’ve never seen one on a keychain, but if you do, send me a link!


Pros

  • Can effectively disable or deter an attacker

Cons

  • Offers very little versatility: You must be able to press the prongs against your attacker and hold them there long enough to deliver enough electrical charge to incapacitate them

  • May not be effective against attacks from behind

  • Must always be fully charged

  • Subject to mechanical failure

  • May not be legal everywhere in the U.S.

  • May not be allowed at public gatherings or on planes

  • Not safe around small children




MUNIIO Keychain














You didn’t expect me to leave our own self-defense keychain off this list, did you? But in all seriousness, I firmly believe this is the safest, easiest-to-use, and most reliable self-defense keychain you can possibly get.

Pros

  • No special training is absolutely necessary to use this self-defense weapon, since using it is simple and natural. Of course, some basic training tips will help enhance your natural abilities. If you happen to have martial arts training, you will be able to use it in even more complex ways.

  • As one of the most versatile self-defense keychains, it can be used effectively even against attacks from behind

  • Can be used for everyday carry (EDC): It’s legal in all states and can be carried onto airplanes

  • Stylish and chic with many design options, and, since it doesn’t look like a weapon, is more likely to be carried regularly by users

Cons
