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.
