It’s hard to find as many survival features in an item as one would in the Flint. 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 4.3 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.
