Your survival can often depend on your ability to start a Survival Fire. Whether you use Waterproof Matches, a Magnesium Fire Starter, an old Bic, or you use a fire drill, you're going to need to be able to build a Survival Fire.
A good Survival Fire Starter is worth it's weight in gold. But regardless of the type of Survival Fire Starter you select, it's a good idea to have a back up Fire Starter available, as well as a package or two of Waterproof Matches. In fact everyone in your group should have a Survival Fire Starter of their own. Just in case.
