The fire starting tools utilize a proprietary alloy of rare earth metals
called ferrocerium. Some of these metals include Iron, Cerium and
Magnesium. When a ferrocerium rod is rapidly scraped, the friction
created ignites the shavings producing molten globulars of burning
metal. It is these long-burning molten globulars of metal that make
a ferrocerium fire starter so effective at catching other materials afire.
