Four Seasons Survival Gear has reintroduced their aluminium Spark Light.This is the same maker of the original Spark Lite except one is plastic(economical,disposable)the other is metal with replacable flints.These are a great quality item that is prized by those who have them.They are listed for $18.00 on their web site.
Is the Spark Lite the best fire starter? For a one handed fire starter the answer is YES!This is not just my opinion either.Backpacker magazine has even stated this.It's size and negligible weight makes it to easy not to have it on you all day-every day.A metal one is just too good to be true.
