Do Not Depend on Thin Ferrocerium Rods as they can Break while Striking. The Ferro Rod is One of the Most Efficient Fire Starters and One of the Most Sustainable & Dependable. A Ferro Rod Doesn’t Run Out of Lighter Fluid, or Requires an Excessive amount of Elbow Grease. Ferrocerium Rods take a Significant Amount of Time and a Sufficient Amount of Use to Wear Down to a Point where They are No Longer Strikable. These are Guaranteed for Over 15,000 Strikes. The Only Challenge While Using a Ferrocerium Rod is How to Manage the Tinder. Over 5,500 Degree F. Showering Sparks from a Ferrocerium Rod Make it Easy with any Dry Tinder. Even Scraping a Knife Across the Rod Will Get Sparks. (Be sure to scrape with the spine of your knife rather than wear down your sharp blade.) You Must Pay Attention to Where you are Concentrating the Sparks and Make Sure you are Using Sufficient Tinder. Best Practices for Using a Ferrocerium Rod are to Hold them as Close to Your Dry Tinder as Possible and Strike in on Direction with Force. Each ferro-rod comes covered in a protective black paint from the factory to minimize premature oxidizing. This coating must be scraped off to reveal the usable silver ferrocerium underneath. After using, simply wipe down with Vaseline or WD40 to protect it from oxidation until you need it next.
