Today we went cross country skiing, we always ski to a shelter, backpack in lunch. When we get to the shelter we start a fire and cook brats or hotdogs. So instead of using matches I had my oldest boy use the flint and steel with a cotton ball soaked in Vaseline and some pulled apart twine as his tinder, this is old mattress twine wanted to see how it worked. The boy did OK he was able to get it to spark no problem and even got a flame on the cotton ball, but he had his whole set up down low in the ashes and as he tried to move it around to his wood it went out, so I had to start it. Photo here is after the fire was burning and the brats and dogs were cooking. Next char-cloth, I think the boy will have better luck with that and cotton balls/Vaseline, also a good hunting knife will work better for him bit more leverage than the flint and steel alone. The metal striker that comes with it is a bit small for him to use.
