How many on here pick up your own flint when you're out in the wild? My wife and I like to take our grandsons out to picnic areas nearby when the weather is nice and there is usually a stream that they can play in. I'd like to learn to recognize flint and be able to pick it up to try my hand at knapping it into useable pieces for my flintlock rifle, like my late grandfather did. I will be watching some Youtube videos I suppose, and carrying a file with me on the picnic trips.
