FOG=Flake Over Grind. That's where you saw a slab and shape it like a point, grind it to a lenticular cross section, and then finish it with a couple passes of pressure flaking. I always kid Eddie about his FOGging and he kids me about beating up a five-pound rock with percussion to make an arrowhead. It's a modern knapping technique, but actually has historical roots. It was used by the Egyptians to make Gerzian knives and by the Danish on some styles of their daggers-they percussioned preforms out to shape, then hand-ground them smooth on sandstone.

I would like to add, that although the initial cost of a grinder may seen high.....some rock isn't cheap, and you will easily make your money back on rock that is not wasted, if used right they last a long time. I recomend #60-#100 grit wheels.
I have also found you can use a wet saw blade for grinding, if held at a 45 degree angle to the blade. This is something that one would have to experiment with to get the hang of it, but it works quite well!
