Why do survival experts recommend fatwood for emergencies?

April 5, 2026

Quick Answer

Survival experts recommend fatwood for emergencies because it is a highly efficient and reliable fire starter. Fatwood contains a high concentration of resin, which ignites easily and burns hot, making it an ideal source of tinder. This natural resource can be found in many types of trees and is often overlooked, but it's a valuable tool for starting fires in survival situations.

What is Fatwood?

Fatwood, also known as cedar knots or firewood, is the resinous or pitchy part of a tree that has died or been cut. It is typically found at the base of the tree or in the knots, where the resin has accumulated over time. To identify fatwood, look for the resinous or sap-filled areas, which will be darker and more aromatic than the surrounding wood. It’s essential to note that not all trees produce fatwood, but many species do, including cedar, cypress, and pine trees.

How to Use Fatwood in Emergencies

To use fatwood as a fire starter, you’ll need to break off small pieces of the resinous material and shave or shred them into fine tinder. You can also crush the fatwood into smaller pieces to create a more uniform texture. A single piece of fatwood can produce hundreds of sparks when struck against a hard surface, making it an incredibly efficient fire starter. To maximize the effectiveness of fatwood, store it in a dry, airtight container to preserve its resin content.

Fire Starting Techniques with Fatwood

When starting a fire with fatwood, it’s essential to use the right technique to maximize the number of sparks produced. Hold the fatwood piece at a 30-40 degree angle and strike it against a hard surface, such as a rock or a metal knife. Aim for the base of the fatwood, where the resin is most concentrated. This will help create a shower of sparks that can be directed towards your tinder material, making it easier to start a fire. By using these techniques and identifying fatwood in your environment, you can rely on this natural resource to help you start fires in emergency situations.
