Knowing how to start a fire using flint is very useful and can save you a lot of trouble.
Steps. Get a knife, magnesium flint fire starter, like the Coghlan's Fire Starter and gather anything that might burn. Scrape the blade on the magnesium, pile shavings on the dry tender. Hold the flint at an angle over the pile, while forcefully sliding your striker along the length of the flint to create sparks.
