Doesn't the lighter fluid eventually evaporate away? Also you can crush, shatter or otherwise break a lighter. Fero rods you can stash away indefinitely and throw into a pack without concern.I never quite understood the use of fero rods to start fire, when Bic lighters or a good butane lighter are so much more efficient and economical, transportable, and useful. A 6 pack or two of Bic’s will last you forever. Or if your feeling old school a nice Zippo with a few spare wicks, flints and a couple bottles of fuel.
