Exotac's Nanostriker XL is among the best firestarters on the market. You want to have fire as quickly as possible, and that requires a good quality ferrocerium rod that emits a high-temperature spark that ignites material quickly. Works even when wet.
A top American product that should not be missing in your outdoor/survival package.
We supply it in orange, so you can find it faster when you drop it on the ground or leave it lying around somewhere.
