I use the STRIKE A FIRE FIRE STARTERs that come 8 to a box. They are sold under the COLEMAN name. They also come under another name... Been using these for years.

We showed up at one spot here in VA and immediately rounded up some downed sticks etc and had a fire going in a snap. The neighbor guy came over and said "How did you do that" haha... He had been trying for an hour he said to get those same downed sticks to burn. Said he had run out of all the papers he could find in his trailer to burn haha...
I gave one of those 8-piece boxes and he got his fire going right away.
Later on that afternoon he comes back over bringing me a new box of them.. Said they were being sold in camp store ...
Said Thanks for the tip...
