ReliabilityMedium reliability
TimeMinutes with dry bamboo; often impossible without it
Materials
- Section of dry bamboo or suitable softwood
- Cutting edge piece (bamboo strip or hardwood saw)
- Tinder packed into or beneath the notch
Steps
- 1Split and prepare a hearth piece with a notch or split that will catch hot dust.
- 2Pack fine tinder into the catch area.
- 3Saw vigorously across the hearth with firm downward pressure.
- 4When dust ignites or a coal forms in the tinder, blow carefully to flame.
- Green bamboo sweats moisture into the dust
- Notch geometry fails to trap powder
- Saw edge rounds off—reshape and continue
- Trying this outside bamboo/softwood regions wastes critical energy
