sorry i can't help but this why i have a fire lighter that makes fire and not sparks...
As you know, a lighter is technically like a firesteel and PJ cotton. A lighter makes a small spark from a flint, and the tinder is a wick covered in liquid fuel. A firesteel needs to be about 50 times bigger than a lighter's flint because a firesteel can make about 50 times more sparks.
Don't get me wrong. A lighter is my number one, but a rugged firesteel as backup gives me a warm and fuzzy feeling.
