One of the things that has made us a successful species is our ability to wield fire. Getting a fire started and variations to make them efficiently and specific to purpose have huge benefits in survival settings and off-grid, no- or low-power scenarios.
Some of the information out there gets used and passed along without a lot of consideration to the conditions, though. I think sometimes we’re just looking for a DIY or a “craft”, especially if we’re on a tight budget, and don’t really test or think it through before we go whole hog. Sometimes we’re overlooking something even more compact or versatile. Sometimes, having two parts to a whole still separated has a lot of value. And sometimes, I rarely even see the most effective helpers mentioned.
