Quick Tips - One Handed Fire Starting:
https://youtu.be/mtjXE2Ww2I8having had a broken wrist for the last 7 weeks i'm oddly interested in this now! my conclusion is; if you have to do anything much to survive; you probably aren't going to.
oh how wise dougs' one handed fire starter and mirror suddenly seem!
note; he's only showing you how to use it one handed, he doesn't actually have a broken arm. unscrewing the match box as he does won't be possible. anything screwed securely, will still be like that when they find your body.
something to bear in mind; try using your techniques and gear one handed.
