Tiller I have had that same theory. I had always thought about trying it. That is when I learn to knapp, and actually have some rock to practice on. I have seen the fluting jigs, and they are pretty neat, but I have always thought about making a preform, and then smacking it. I have another idea too, may or may not work. I thought about heating a point up, and then taking a stick that has been soaking over night in water, and laying in on the the base of the point and spalling a flake off, and then doing the other side. I know, I know, yeah, I do have some strange ideas now and then......
But......has anyone ever actually tried it? Just imagine if the Wright Brothers has gone along with the current wisdom of the time......
