When I was a Scoutmaster I would always get one of these kits for each new boy that would come into my troop. We never carried lighters, and only 3 matches total. The whole purpose of this was to force the boys to learn that you can make a fire you just have to know how to do it.
The char cloth that you use with flint and steel is very important to have. I always make a bunch and have it with me whenever I am in the woods.
