3 Reasons Why Fatwood Is Worth It

Natural Water Repellent
Fatwood, or heartwood, is valuable because it has strong interior tissue making it wind and water-resistant. It means that it will still catch fire even in the rain or snow.
The last thing any hiker or camper wants to do is try to find dry firewood to get a flame going. A few pieces of fatwood go a long way to keeping you warm.
How long does fatwood last?
We have no idea, but we think indefinitely. And a little bit of heartwood can go a long way.
The tree itself can live up to 500 years and takes 100 to 150 years to mature. And the stump never rots because the hardened sap essentially preserves it.
100% Natural
Of course, it’s environmentally safe because it’s natural wood. But you don’t have to be a traditionalist or conservationist to appreciate burning a clean fire source.
Some fire starter materials come with the dangers of chemicals, propellants, and toxins. Burning fatwood not only smells better but also better for your lungs.

Battle of the Firestarters

Conventional fire starters are pretty susceptible to moisture. Fatwood has the benefit of hardened sap, which makes it water resistant.
And, if you don’t have a lighter or match on hand, making a fire the hard way is less hard with fatwood.
Fatwood vs Chemical Fire Starters
The temptation of instant fire is just too much for us to handle sometimes. But fires built with solid-fuel compositions will release toxic chemicals that you, your family, and your pets may have to breathe in.
Fatwood has a natural fragrance and is entirely non-toxic (though not scented like candles).

Fatwood vs Newspaper
100% there is a joke in this, but honestly, lighting fires with an old newspaper is not practical or safe. Burning a newspaper produces a dumb amount of ash, dust particles, and poofs out of existence awfully quickly.

Fatwood vs Birch
Birch is 100% natural and safe, and easy to burn. However, a lot of birch bark out there has been illegally harvested from live trees.
Fatwood comes from stumps of trees that’s already been cut down or fallen.
Fatwood vs Magnesium vs Traditional Flint
We watch survivalists, and competition contestants use flint or magnesium blocks to get quick access to a fire. But, in a real emergency, it takes time and much-needed energy sometimes to get it to strike just right.
Striking magnesium takes some level of skill, too. It burns hot because it is a metal and is almost impossible to douse with water.
