The Exotac fireROD™ fire starter is designed to be used in tandem with your knife. Using the spine of your knife, you simply strike the fireROD™ to easily create a spark. The top cap is removable. Unscrew it and you'll find a small compartment that can easily hold two quicklight tinder tabs (included) or tinder of your choice.
The fireROD™ is CNC machined, in house, from USA high-grade 6061 aluminum then anodized for protection in one of three signature Exotac® colors. And the 5/16" ferro rod is not only waterproof but replaceable as well.
