For Low-Key Defense, Use Pepper Spray Keychains
When you are responsible for other people, protecting them from wrongdoers should become second nature. This includes defending them during a dangerous situation. An effective defensive weapon does need not to be big or heavy. In fact, pepper spray keychains are able to repel attackers adequately, especially when you are proficient at using them.
These are non-lethal weapons, whose effects are temporary and do not cause life-threatening harm. Their size makes them unobtrusive, and placed in your pocket, bag or belt clip for easy access, will allow a quick response.
Just remember to get your client, or whomever you are chaperoning, out of the way when in defensive mode. And then, with a multicolor Wildfire 1/2 oz. 18% pepper spray, you can blast the target from 6 to 8 feet away until his eyes slam shut and he is gagging from the extreme heat. This hot pepper spray comes with a safety lock, and is good for 6 to 10 bursts.
