Abstract
A fire igniting device which includes a rod of an ignitable material, particularly magnesium, and has a pyrophoric element adhered to the rod along its length. A head is secured to the rod, and also may be fitted to a case, so that a spent rod can be removed and discarded from a handle, and another rod installed. The case is adapted to receive the rod during periods of non-use, to protect it from contaminants; and, during use, the case may be fitted to the other end of the head so as to increase the effective length of the head and provide a more comfortable grip to the user. A metal striker for striking the pyrophoric element is conveniently tethered to the case. Magnesium shavings are scraped from the rod, and are then ignited by striking the pyrophoric element with the striker. The fire igniting device may be incorporated into the handle of a survival knife, whereby the handle functions as a case for the magnesium rod during periods of non-use.
