How to Start a fire with a "flint on marcasite" method

In this Disaster Preparation video tutorial you will learn how to start a fire with a "flint on marcasite" method. Mal Stephens, head instructor of Maine Primitive Skill School presents this video. Marcasite is a form of iron pyrite and you can get friction fire from fine grained iron pyrites. For the flint, you can use any hard stone. For the burning material, find some tinder fungus. Now hold the marcasite immediately above the tinder fungus and strike it with the flint. The sparks from the marcasite will make the tinder catch fire. You can scoop out that portion and use it to light up a bigger fire.
