Building on the traditions of the mid-1700's, the Fire Piston uses heat generated from rapidly compressing the air to ignite a piece of tinder, which can be used to light kindling. Constructed from a solid piece of 6061 aluminum, with brass end caps, the Fire Piston is sleek and compact. Built to last a for a lifetime of camping and hiking, and perfect to keep in your emergency pack, the Fire Piston comes in a soft drawstring bag, with an information card, space o-rings, and a piece of charcloth.
