thanks guys. hammerstones have the tendency to leave a heavy ridge so they are ideal for setting up the piece for fluting.the side with the multiple flutes was actually fluted 3 times. the first one ran down the center leaving two more strong ridges ready for fluting. i think the reason it snapped was because the first flute left the ripples and the last flute dove in at that point.
john with the way you took to knapping i think you would have no problem adjusting to abo tools. the only difference with abo stuff is the density so you need to swing a little harder , adjust your platforms and also be able to adjust to the different tools inconsistency in density and shape. im still learning myself. especially with the hammerstones. if im not careful i find it very easy to create a bulbed platform that needs to be stitched out. when that happens i lose a lot of material.
