Things to consider before buying a self-defense keychain
Method of defense
This is where you ask yourself what tool you wish to use for defense. Do you want to keep it simple with pepper spray or a small taser? How about a tiny blade or a kubotan for really showing those dastardly fiends who is boss? Pepper spray appears to be the most popular choice for its cost and ease of use, but a few acquaintances of mine prefer defense tools that are a bit more on the offensive side.
As you sift through the myriad of options, you should also consider the legality of your desired tool in your region and how easy it is to use. Pepper spray and stun guns are fairly brainless and nearly eliminate the margin for error. On the other hand, a kubotan, blade, or plastic knuckle duster may force the user to get up close and personal with the offender and aim for pressure points to discourage their attack.
Portability
Here is where you determine how easy a defensive keychain is to lug around in everyday life. As the category suggests, they’re small enough to be easily bound to a keychain or lanyard and will be miniaturized caricatures of their standard-sized siblings. Still, each user may have slightly varying needs.
Some users who prefer stuffing their keys in their pockets will appreciate the slim-fitting design of some blades and kubotans, whereas folks who use bags can afford the added bulk of a pepper spray can. Alarms are roughly the size of a car key fob and can be placed anywhere on a person. Just be cautious not to set it off accidentally, as a small handful of consumers have done.
FAQs about self-defense keychains
Q. How much do self-defense keychains cost?
A. Thankfully, these items are defensive tools that won’t break the bank in the manner a firearm or quality standard-length blade would. Nearly all defensive keychains sell between $10 and $20, with multi-item bundle deals being sold from $20 to $30. Our Best Value-winning Sabre Pepper Spray stickers for an inviting $10.
Q. Are self-defense keychains legal everywhere?
A. It depends on the method of defense and location. Kubotans are generally legal in all U.S. states, but some jurisdictions may pose minor restrictions. Spiked kubotans are illegal in the U.K., with blunt variants still hotly debated. And they’re too short to be legal in Canada. Knives will fall under the same restrictions as other blades, just as plastic knuckle dusters are bunched in with brass knuckles.
Q. Can I take self-defense keychains on a plane?
A. Just about all defensive keychains will face the same travel restrictions on planes, meaning knives and kubotans are often barred from carry-ons and can only be checked in. Pepper spray containers up to four ounces may also be checked in. Stun guns and tasers must be rendered inoperable.
Q. How effective are self-defense keychains?
A. Like any weapon in the hand of a well-versed individual, any defense tool, no matter how small or simple, can be used as a brutal force multiplier. Even basic and polarizing devices such as kubotans can deliver painful jabs to pressure points and fleshy areas, greatly discouraging attackers.
Final thoughts
The Cymme Safety Keychain Set was an easy winner. It gives the average consumer nearly every defense option possible in one fell click and at a reasonable price. If you had to have one, it’s hard to beat the value of SABRE’s Pepper Spray, given its range and accuracy for $10. Of course, why not hop on the bandwagon and try a kubotan from the KSKPP Protection Keychain Pack, which gives you nine tools to deter attackers in painful yet nonlethal jabs.
Methodology
This guide has been curated primarily through extensive research, diving deep into manufacturer specs and, more importantly, consumer feedback to determine which keychains are truly worth investing in. The best items would be the most acclaimed and trusted defense tools with stout build quality and ease of carrying on a day-to-day routine. Items with little-to-no consumer input or reportedly shoddy quality control issues were usually ignored, as we prefer that our readers invest in items that can last for ages.
Amazon continued to serve as our primary encyclopedia of manufacturer information and customer input, but quick searches revealed Blade HQ as another source of top-notch products not found elsewhere.
