Just a video to show that you don't necessarily need Flint and steel to make fire. Here I use an agate and part of an old file to ignite my charred material. My actual total time from start to flame was around three and a half minutes. The video is edited down since it's not the most exciting thing to watch a guy bang a rock on a piece of steel. You can do it too, you just need some charred material and a little practice.
