Something that I have been seeing more of recently in survival kits is Tinder Quik, it has come in 3 of my last 4 survival kit purchases. Basically its cotton wool impregnated with a wax based fuel that takes a spark really well and burns for around 2 minutes, long enough to get kindling on and the fire going.
Normally you get 4 tabs in a kit with a Fire Lite™ a one-hand-operable fire starter that is easy to use and produces a powerful shower of sparks, personally I think that the size to weight to usefulness ratio justifies adding a few extra tabs to any kit.
