The NEW Light My Fire firesteel is a real winner, it has a great new ergonomic handle and a great new, more effective striker. The striker handle also has an emergency whistle built into it so you can always summon help when needed.
It produces a 3000 degree spark and should last 12,000 strikes. It is water and oil resistant and won't break in tough conditions. It is designed to tolerate temperature fluctuations and is safe to use as it won't ignite itself.
ABS plastic handle and its own striker (you don't have to use the blade of your knife)
