When it comes to making fire, a disposable lighter will come into your mind at first. However, lighters and matchsticks are vulnerable to wind and rain in severe weather. Flintstone, which is the most primitive tool to make fire, is the most reliable way to make fire in outdoor activities. This is what we call outdoor survival flintstone. Scrape the surface of a new flint several times to remove the black oxide layer and then you can strike sparks from the flint. Scrape the magnesium rod quickly at about 45-degree angle with a blade to effectively produce sparks, and the blade must vertical to the scraping surface. In this way you can strike sparks and burn magnesium. * FAST SHIPPING Color: magnesium rod grip (green), scraper (silver) Material: metal, magnesium, etc. Magnesium rod diameter: 6.5 mm Length: about 8.7 cm Package includes : 1 x Magnesium flint AND 1 x Metal scraper
