The Aurora Fire starter is a survival tool of the highest order. It's designed with a built-in guided striking blade and ferrocerium flint steel rod with magnesium in its composition. The result is a product that yields sparks as hot as 5000 degrees Fahrenheit. Set it against your starting material, whether it's cotton balls, lint, toilet paper, or birch bark, and then scrape the flint rod against the blade. Aim the sparks toward your starting material, and watch as the flames grow higher and higher.
