As tinder-igniting campfire starter rods it is sold under such trade names as Blastmatch, Fire Steel and Metal-Match for survivalists and bushcraft hobbyists. Some manufacturers and resellers incorrectly call them "magnesium" rods. Some manufacturers combine a strip of ferrocerium along with a strip of magnesium in the same item, to be used by scraping off flakes of magnesium and then striking the ferrocerium with a knife. The sparks from the ferrocerium will ignite the magnesium, which will in turn ignite the tinder.
