Cactus - Fatwood is a pine wood, approximately 8" in length (approximately 3/4" in diameter), which is hand-split from the stumps of pine trees that contain a high concentration of natural resin. This organic, 100% natural resin allows the Fatwood to be started with a single match and gives a sustained flame.
In South Georgia where they have 10's of thousands of acres of pine forest grown for commercial use, Power Poles, Pulp wood for the paper industry, lumber, etc. Those people call fatwood "lightern" same stuff , never heard fatwood till today. Always been "lightern" to me , and many others in the south.
