S.O.G SOGFT1001CP Flint Black Aluminum 4.30" Long. The Flint packs enough survival and defensive components to get you through the night or away from danger. In a tool the size of a pencil, the Flint has a built-in fire starter, steel wool tinder compartment, carbide-tipped glass breaker and safety whistle. Weighing in at less than an ounce and measuring 4.30" long, it's small enough to be carried on a lanyard, in a pocket or in a pack. Wherever the destination is, it's always nice to have a backup plan. Tools: Fire Starter, Steel Wool Tinder Compartment, Carbide-Tipped Glass Breaker and Safety Whistle.
If needed this little item held in your hand would do a lot of damage as a striking device as the carbon glass breaker would work the same as the end of a Kubaton and could end the threat against you. So if carried as a key chain it is always there.
