Coghlan’s Flint Striker is a rod made of magnesium with a striker attached with a piece of cord. It is simple to operate. You just take the striker and hold it in one hand with the word UP facing the top of the rod. Make sure the serrations are in contact with the rod and pull it down the rod. This results in a shower of sparks that can help you start your campfire. The best thing about the Flint Striker is it is completely safe unless your using it. It is non-flammable and can also work when wet. That means if your pack is wet from your hike, you can still start a fire if you can find some dry wood. Always works - in any weather or altitude. Lasts for thousands of strikes!.
