What is the most reliable way to start a friction fire using foraged materials?
Not necessarily just the overall technique (ie: "drill" or "plow" or whatever); it's good to compare specific variations of the technique.
Assume that you can process the materials with a blade. It is only fine to use other tools if they can be made from what you find (ex: preparing a hearth board days or weeks ahead of time).
Assume I have the most common knowledge that you can expect someone to have after watching 2 or 3 videos each about fire drills, plows, and saws.
