Fire is very important in survival. Not only does it do the obvious by keeping you warm but it boosts your moral considerably. If you have ever been in a situation where you couldn't get a fire started and got yourself cold, wet or hungry with only food available that needs cooked, and then were able to finally get a fire going, you know exactly what I am talking about. I have been in this situation so I know the importance of fire. I have had Bic lighters and fancy rocket lighters fail on me. So when I am headed into the backcountry or during survival training, this fire kit is what I carry. On long treks I don't take both fire kits but I always, always, always have at least 4 ways to start a fire on me when I go out, in addition to knowing how to make and use a bow drill and/or a hand drill.
