bayite Small Ferro Rod Survival Drilled Flint Fire Starter with Toggle Hole for Paracord Bracelet Necklace 1 Inch Pack of 6

Diameter: Diameter: 5/16inch(8mm)
Length: 1 inch
Material: Ferrocerium
Diameter of the hole: 4mm

HOW TO USE:
1. Hold the ferro rod close to the tinder at about a 45-degree angle. （Dead grass or weeds, fine, dry wood shavings, twine pulled apart, dryer lint or cotton balls... all make good tinder.）
2. Place the scraper near the top of the rod (so it makes solid contact with the rod).
3. Pull the rod back (away from the tinder) with a slow and steady motion.

Tip:
Many people will hold the ferro rod next to the tinder and rub the scraper toward the tinder. By pulling the rod back (instead of rubbing the scraper forward) you'll create a spark at the same place. But you'll do it without risking bumping the scraper into your pile of tinder and scattering it all over the place.

PLEASE NOTE:
Because Ferro rods contain iron, they're often coated to prevent oxidation. You'll need to scrape away the coating to expose shiny metal before first use.
