The fireROD is Exotac's version of the Habilis Evolution Fire Tool. This is an excellent fire starter that has the added convenience of a small storage capsule handle design. The capsule has a threaded, o-ring sealed cap that is perfect for storing petroleum jelly coated cotton, etc. The capsule is roughly 7/8" deep and 3/8" in diameter by our measurements. The fireROD ferrocerium rod is replaceable.
