Things You'll Need
Instructions
Gather your tinder, kindling and wood for burning. Keep them in separate piles, right next to where you plan to shave off the magnesium.
Dig a slight depression in the ground to catch your shavings. If this is not possible, use a flat piece of wood or cardboard or some other platform to keep them all in one place.
Take out your knife. Holding the firestarter upright, with the flint side facing you, shave off a small pile of magnesium onto the ground or the platform you have set up. Try to keep your knife blade positioned at a 90-degree angle to the firestarter to prevent it from catching on the notches your knife will make in the magnesium.
Pile some tinder on top of the shavings.
Hold the firestarter with the flint side facing outward. Take your knife and run it rapidly down the flint so it produces hot sparks. It will take you a few tries before you get the spark you need, but it should happen rather quickly. The magnesium will ignite and the tinder will catch right away. Be ready to pile on more tinder and kindling.
