Since I got back from the Tucson Gem & Mineral Show I've been keeping a secret. But I can't keep it any longer or I'll explode. I found some rock that I dream about, but it's better than that. At the bottom of a rock pile I dicovered a few pieces of blue knapping rock! Naturally, I dove on it like a hungry cat on a fat mouse. You see, blue is the rarest color in flintknapping rock. To confirm that, all you have to do is see the absence of blue arrowheads or stone knives in your collection - or go to a museum which has stone artifact exhibits. You're not likely to see blue. In any case, I have knapped a couple of points from this rock and am so happy with them that they found their way into my own Keeper Case. Worry not. Soon there will be a blue arrowhead or two and perhaps a blue stone knife for sale on my website. Then a blue arrowhead can find it's way into your Keeper Case, too. This is some very cool flintknapping material. Is it flint, agate, or jasper? Where does it come from? Those secrets will be revealed with the first posting.
