Make char cloth for flint and steel
Char cloth catches a spark instantly and buys you a full ember to blow into flame.
PaleoHikerMD — Making a Better Char Cloth
Step-by-step
Cut 100% cotton (old jeans, canvas) into 2-inch squares.
Pack loosely into a small tin with a single pin-hole punched in the lid.
Set the tin on coals — smoke will jet from the hole.
When the smoke stops, pull the tin off and plug the hole with a twig; let it cool sealed.
Cloth should be uniformly black, still flexible, and tear cleanly.
Warning: Opening the tin while hot lets oxygen in and burns your char to ash.
