We have countless hours practicing with all the popular ferro rods and the Light My Fire ferro rod is the one we carry in our packs and depend on.
 
When our Cyclone triple torch butane lighter won't work due to extreme conditions, this is our dependable fire-starting backup. It works in icy temps, dangerous winds, at any altitude, and is rated for up to 3,000 strikes. We think they nailed the design making it very comfortable in the hands which makes it easier to use and more effective than other ferro rods. It includes a built-in whistle and is made in Sweden from bio-based plastics. Most importantly, we consider it the best for our use and we are never caught without it.
