We set out to create a firestarter that is high quality, ultra-small in size and completely self-contained. The nanoSTRIKER™ is the result. Sacrificing neither form nor function, its unique all-in-one design puts all the tools you need to start a fire into one tiny package. At the end of the day, this little tool can be collapsed and returned to key-chain ballast duty. Specifications: Striking Tool: The nanoSTRIKER XL™ includes a stainless steel and tungsten carbide striker that will outlast even the fiercest of fire-craftsman. 1/4" Ferrocerium Rod: The included Ferro rod is not only waterproof but replaceable as well. Simply unthread it from the body of the fireROD™ and thread in a replacement rod. Anodized Aluminum Body: The nanoSTRIKER XL™ is CNC machined, in house from USA high-grade 6061 aluminum then anodized for protection in one of four signature Exotac® colors. Ferocious Spark: Our unique striking tool design and ferrocerium rod composition creates the most prodigious spark for its size! Made in the USA
