Knowing how to start a fire in the cold is an essential survival skill. And with ferro rods, even bushcraft beginners can light a fire in bad weather.
Once you have a good site, make a fire pit with dry wood and stones and gather your tinder materials. Then, for a fool-proof flame, use the Pathfinder Mini Inferno all-weather pads.
Get a flame going by holding your knife blade or metal tool stationary and then pressing the rod against it and drawing it toward you.
This should throw sparks that land on your tinder and Inferno discs.
