I use rubber, either rubber bands or a piece of inner tube, to create a longer lasting flame to dry slightly wet tinder/kindling. You really can't light it without a lighter, but once it catches stand back. If it is placed in the center of a pile of twigs, it dries the twigs above with heat while the twigs below catch the "drippings" and eventually also catch on fire.

I always carry cotton balls/petroleum jelly in a film canister.

And the trick birthday candles, the kind that can't be blown out, are a good one time use firestarter also.
