2. Kaiyuan Dynasty Self Defense Kubaton Keychain


The Kaiyuan Dynasty Self Defense Kubaton Keychain helps you to do some serious damage with just your fist, even if you aren’t a trained fighter. The long spike fits in the palm of your hand. Then, the dual spikes slip out from between your fingers when your fist is closed, allowing you to hit someone with added emphasis from both the top and side of your fist if need be. It’s also important to note that the side spikes are removable if you find them too bulky on your key ring.

3. Swiss+Tech Silver 7-in-1 Key Ring Multitool


While not designed specifically for self-defense, a Swiss Army knife-type tool could help you out in an emergency. This Swiss+Tech Silver 7-in-1 Key Ring Multitool boasts a knife, two screwdrivers, an awl, an LED flashlight and a bottle opener. The blade and other pointy accessories can help you harm someone who is attacking you. In addition, the flashlight may help you stay safe in nighttime situations. And, when you aren’t facing down your enemies, this multitool will also come in handy for other everyday events, whether you’re camping and need a light or you just need a screwdriver around the house.

4. MUNIO Self Defense Kubaton Keychain


For a self-defense keychain that doesn’t look like a weapon hanging on your key ring, look no further than the MUNIO Self Defense Kubaton Keychain. This piece was designed for two functions. First, the plastic piece can be gripped in a fist with the pointed side down, allowing you to jam it into your attacker’s body. Second, this keychain has three keyrings on the other end, and that isn’t a mistake. That’s to give you plenty of room to whip your keys at your attacker after or before you’ve stunned him or her with the pointy keychain. In addition, this self-defense tool comes in several different designs, so you can pick one that fits your style.

5. Coghlan’s Function Whistle


Conventional wisdom says that if you can’t overpower an attacker, the best tactic is to try to make as much noise as possible in order to alert those around you. That’s why having a whistle on your keyring is always a good idea. The Coghlan’s Function Whistle not only includes a shrill-sounding whistle, but it also boasts a magnifier, a thermometer and a compass to keep you safe in all types of outdoor situations. And, because the keychain comes with a lanyard and not a key ring, it can be attached to your keys, coat or bag, too.

Trusted by police and consumers around the world, the Mace Brand Self-Defense Pepper Spray features an impressive 10-foot powerful stream delivery, so that you can engage your target from a safe distance. It can easily attach to your keychain or safely stashed away in your backpack, purse or pocket. A flip-top safety cap prevents accidents or misfires when stored in your pocket or bag.

8. EIOUMAX Portable Self Defense Key Chain


Made with solid aluminum, this lightweight but lethal self-defense keychain is the perfect tool for quick escapes.

9. ASP Palm Defender


The ASP Palm Defender makes significant improvements on normal, plastic pepper spray keychains. That’s because the irritating spray is housed in an aerospace aluminum canister with solid brass accents. This adds durability and allows you extra defense against attackers as you can use the canister as a striking weapon. The 0.10 ounces of the 10 percent oleoresin capsicum formulation provides three half-second bursts in each keychain, although replacement canisters are available if you need them. Do keep in mind that this keychain is not available for purchase in certain states.

10. Thopeb Self Defense Siren


What’s better than a self-defense alarm that makes loads of noise? A self-defense alarm that makes loads of noise and flashes bright lights when activated. That’s exactly what the Thoped Self Defense Siren does. Simply pull out the loop on the top of the device to start the 130-decibel wail and strobe. Noise at such a decibel level can be heard up to 1,000 feet away. Put the pin back in place to deactivate it and reuse the alarm again in the future. As an added bonus, this self-defense keychain can also be used as a flashlight between emergencies.

11. Gerber GDC Zip Blade


Made with stainless steel and easy to conceal, no one will ever know this innocent-looking lanyard is actually a sturdy zip blade. It features a one-of-a-kind design that helps keep the blade in place and can also be used to open letters and boxes. Keep in mind, however, that the blade length is just 0.68 inches, so this shouldn’t be thought to be a functional blade in circumstances outside of self-defense and box cutting.

13. Geekey Multi-Tool


The Geekey Multi-Tool definitely isn’t a standard self-defense keychain. It doesn’t have a built-in stun gun, pepper spray or flashlight, but it does have several innovative functions while appearing like a standard key. Most importantly, the key features a box cutter that could do damage to an attacker’s skin or to any ropes he or she may use to tie you up. In addition, the Geekey boasts a bottle opener, can opener, wrench, screwdriver, ruler, file, wire bender and wire stripper.
