Nice picture!!

Yea Bee the above technique works great just practice it some to get good at it. A small piece of fluffed cotton with Vaseline the size if your fingernail is plenty to practice with. I’ve even been known (your on your own here) to practice with very small pieces on the bottom of a cookie sheet or an iron skillet to keep it from burning things that should not get burned.
Oh and I made what I think is a better scraper out of an old sawsall blade I like the way it sparks better than the factory one.
Anyway have some fun with it and get comfortable with it, because it is a dependable method of making fire.
