The UPS truck stopped out front with a couple of packages... wheeee! They were full of hand-sized spalls of novaculite chert and keokuk burlington. One of the knapping suppliers had written a tantalizing advertisement for their rock... "Knaps like butter, Chips to a Glossy Finish!" A month later, and $100 poorer I was the proud owner of a couple dozen spalls of quality knapping stone.
I know this sounds funny to many to spend a hundred dollars for stone. (I've spent much more at times.) This was an adjustment for my wife. But, business-wise, all I need to do is make 2 or 3 items and sell them at an event and the cost is covered. Despite the cool, no cold, weather I was anxious to break some rock. One spall spoke to me and revealed that it would like to be a tomahawk blade...and so it became. You know that is one thing I have learned to trust while knapping...my instincts, or inner voice. Particularly as you are doing some delicate work the voice will tell you, "Put it down, you are going to break it with your next strike." It's just a whisper. If I ignore it, sure enough, I suffer the consequenses. After awhile you learn to trust in that still small voice...the Great Spirit?
