Key chains are not just for keys anymore, at least not for those of us with survival in mind. Since you have your keys with you during pretty much all of your travels that include leaving the house, it makes sense to outfit your key ring with some handy tools to help get you through whatever you might face in the course of a normal, or abnormal, day. Adopting your own do-it-yourself survival key chain to include life-saving items can prove very useful and is something to consider doing if you have not done so already.
One possibility for a survival key chain is including self-defense items. Whether it is with a cute cat or a wrinkly bulldog, hit \'em where it hurts with a defensive key chain. Personal protection key chains are available for sale that offer finger holes for grasping and striking anyone who poses a threat to you. You could opt instead to hold your keys between your fingers and swing, but those keys are prone to moving and possibly crushing your fingers whereas a defensive key ring is made for the purpose of striking an attacker while preserving your flesh and bones. Other defensive options include pepper spray, small stun guns, kubotan, or a monkey fist with heavy duty contents.
Having a multi-tool on your key ring can also be quite helpful as it allows you to have multiple options at your fingertips. Since multi-tools can vary slightly in what they contain, be sure to shop around to find one that suits your needs. Components such as a knife, saw blade, scissor, screwdriver, awl, leather punch, and flashlight are just some of the things that can be of great use to you. If you are unable to find a multi-tool you like with a flashlight, adding a separate one is a good idea as well. Having a flashlight somewhat larger than that on a multi-tool will enable better vision in darkness or it can also serve as a backup so you are never without light.
Something else to remember to include is paracord. You can make or purchase a fob to attach to your keychain so you will always have access to rope. A good rule of thumb when purchasing paracord is to remember that for every one inch of tied cord, approximately a foot of length is required. With that in mind, if you buy a fob that is tied in a cobra stitch to be about three inches long, you will have three feet of cord. If you want more than that, craft our purchase your fob accordingly. Carrying a monkey fist made of paracord is also an option.
Some other items you might wish to include are: a whistle for alerting others of danger, a compass for finding your way, a carabiner (which can be your base) for fastening and/or climbing, a magnesium fire starter or waterproof lighter, screwdriver keys, tweezers, a pry bar or widgy, and whatever else you can think of that may be of use. In truth, there is a longer list of things that might have a place on a survival key chain than there is room to put them there. It is up to you to decide what you need, what you can sacrifice, and how you can bring it all together on a small metal ring that will still fit inside your pocket without risking alerting others to the items you carry.
