A combination of gasoline lighter, flint and match. Constructed of a steel tube, at the end of which is a cotton wick and a spark igniter.
The match and the wick are constantly immersed in gasoline. To light a fire, you have to unscrew the cap, take out the match from the petrol and make a spark by rubbing the spark plug on the flint.
If you run out of gasoline, you can start a fire using just the flint.
