From my boy scout days... simple 1,000 strike flint & steel with a zip lock bag of dryer lint (only takes about a fanned out quarter size of lint). Tender/Kindling as appropriate. I've had a bag of lint tucked in my go bag for years. It regularly burns homes down, highly flammable. (Lint, not MY lint)
