The Exotac NanoStriker XL performs just like the original but with a larger rod and striker handle. The extra length adds just enough heft to ensure it's easier to use without becoming too big or bulky and still fits on a key chain. The larger design is easier to grip and increases the durability and longevity of the product. The striker handle is 46% bigger, making it easier to grip. Slowly scrape shavings off the rod into a small pile. Use these shavings on top of your tinder bundle for even better sparks. Use the nanoSTRIKER to light gas stoves, alcohol stoves, fuel tablets, BBQ grills, etc. Burns at nearly 5500°F (3000°C). 1/4" waterproof ferrocerium & magnesium rod. Ferrocerium rod works when wet. Lightweight anodized aluminum body. Ultra-sharp tungsten carbide striking tool. More than 3000 fire-starting strikes per rod. Replaceable ferrocerium rod.
