Fire isn’t more useful than when you find yourself in a survival situation. Perhaps you believe lightning fire won’t be a problem as you always carry a lighter or matches. Lighters run out of fuel, get wet or perhaps stop working. Matches may become useless by staying in your pocket or if exposed to rain, snow or submerged in water. Never depend on matches as your exclusive method of fire starting.
Bring alternative ways of starting a fire like a magnesium stick with a sparker. The magnesium stick is straightforward to use and is great at starting fires even if the tinder is damp because it generates a flame source of over 2500°C. Believe it or not, magnesium stick is my primary fire starter even if i absolutely love primitive methods such as the bow drill.
In order to start a fire you can even use cotton balls which were soaked with petroleum jelly (vaseline). Collect dry tinder, break up the cotton ball somewhat, and put close to the tinder. Hold the magnesium fire starter stick block in one hand and the knife in the other. Scrape small shavings off along one side over the cotton ball. The scraping puts small particles of magnesium on the cotton ball.
Using the striker strip and the back of a fixed bladed knife apply pressure and push the knife blade along the striker toward the cotton ball. One or two sparks will ignite the cotton. A 2×2 cm ball will burn 5 to 10 minutes, long enough to ignite even a damp tinder.
Never use the back of a folding knife blade unless it has a locking mechanism. The blade can fold up on your fingers.
Remember: it’s essential to train with the magnesium stick wherever possible so during a real life emergency, you’ll start a fire faster.
