The ultimate Flint and steel kit. Each kit contains a custom cut piece of Ohio flint, specifically selected for having no inclusions or fractures( this thicker piece of flint allows for repeated heavy striking and reliability). A 3" hand selected metal file that has one edge ground to the perfect edge for creating sparks, while allowing the rest of the file to be used for other tasks. A 3" hardened tempered nail( in case you are injured and lose use of one arm, you simply drive the nail into a hard surface, place char cloth under and strike with flint) . 5 pcs of high quality char cloth. 1 JKSB Fire Cube( burn time up to 15 minutes) All enclosed in a metal tin that you can utilize to make char material!
