That's very generous of you Bob! I'm not terribly experience with it, so technique could certainly be part of it. I can get it to throw a spark, but only just. It takes a quite a few goes fairly hard and fast to get anything. We couldn't get the char cloth to catch at all. My wife went to a B.O.W. class last year and did it there. She was able to get a spark there, which is why we were thinking it might be the flint. The set was from Townsends, which was recommended to us. She liked the flint she found on that site because it was larger pieces so it'd be easier to hold, but now I'm wondering if that maybe harder to strike correctly? I do think a larger strike would help too, I have an old file I can use. Do you to do anything special to it?
