Ferro Rod Care & Tips & Tricks

The invention of ferrocerium nearly 100 years ago transformed the way we light fires in the woods. Not only does it power your trusty ferro rod, but it’s also how a BIC lighter makes its sparks.

Ferrocerium is a highly reactive material. Any part of the rod where the protective coating has been scraped off will oxidize when exposed to air, causing it to lose performance. This is the reason why those first few strikes never seem to spark as much.

Long-term exposure to fresh water can cause surface rust on the rod, sometimes leading to pitting that makes it less smooth to strike. Fortunately, a few scrapes will easily remove the rust.

The biggest threat to ferro rods is salt water — it will corrode the rod quickly, leaving nothing but dust! A common mistake is storing a ferro rod in a leather knife sheath, where sea spray can reach it. If you’re near or on salt water, always keep your ferro rod dry in a waterproof bag, especially if it’s your primary fire-lighting method.

Top Tips for Extending the Life of Your Ferro Rod

• Stick to one area — There’s no need to remove the black protective coating from the entire rod. Keeping most of it intact helps protect against water damage.
• Maintain even pressure — Don’t overload the rod. Applying steady, moderate pressure prevents bumps from forming, which can make it harder to generate sparks later.
• Avoid leather sheaths in storage — Keep ferro rods out of leather sheaths during long-term storage, as leather can hold moisture and accelerate corrosion.
• Use a clear nail polish coating — For saltwater environments or long-term storage in damp conditions, apply a thin layer of clear nail polish for extra protection.
• Coat with Vaseline — In wet conditions, a light coating of Vaseline works for short-term protection. Before use, wipe the Vaseline onto your tinder to aid ignition.
• Use long rods wisely — With larger rods (like our 8" Beast Fire Starter or 6" Hive Fire Starter), it’s often unnecessary to use the full length. Many people use the first few inches, then snap off the worn end and continue working up the rod.

Ferro Rod Use — Tips & Tricks

You can use the spine of your knife to create sparks, but I usually prefer the provided strikers. Here are a few of the ways I like to use them:

Finding the bite point of the strikers: Forest Fundamentals strikers have a burred edge on both sides for left- and right-handed users — this is the edge used to create sparks.

The Push technique: This is the method I find most natural. Hold the rod in your non-dominant hand and place the scraper at the top of the rod, near the handle, with your dominant hand. Tilt the scraper slightly forward to find the bite point, then push it firmly along the rod. I prefer this technique when I have a large amount of tinder set apart from my fire lay — there’s nothing worse than knocking over a perfectly built tipi of kindling with an over-energetic strike.

The Pull technique: Place the scraper next to your tinder bundle with your non-dominant hand. Hold the rod in your dominant hand, lay it against the scraper, and pull back. This produces a consistent shower of sparks in a focused area — perfect for fragile tinder bundles such as scraped silver birch fibres.

The thumb pivot: This is a precise technique that helps preserve the life of your rod, though it takes practice to master. Hold the rod near the end with your non-dominant hand and grip the scraper firmly in your dominant hand. Place the back of the scraper against the thumb holding the rod, then pull back, pivoting the scraper on your thumb. This leverage focuses greater force on a small area, producing strong sparks with minimal wear.
