NW Primate has a YouTube channel with a lot of really good Friction and Percussion fire techniques. In this one he uses a piece of metal window screen to keep the char in the tin.
Nice find Dux, it's always good to find a new clever idea to make survival just so much easier and more reliable. Nice background music also. I'm saving that clip onto my computer with my Youtube downloader
Amazing! And, truly, "A wise man knows that he knows nothing at all"...so much yet to learn. And, yes, that background music is great and I enjoyed it as much as the video.
