Cut and Ground Preforms
*We suggest you DON'T order SLICES/GROUND PREFORMS WITH RAW ROCK. SEPARATE ORDERS WOULD BE IDEAL. If you take the risk and order them together we WILL NOT REFUND OR RESEND the MATERIAL that got damaged!**
Education time: When it comes to ground preforms there are different shapes and angles for different goals. The ones I make are for bigger pieces like knifes and so called spear points, with curves and angles like what would be used on Danish daggers. You will notice that the flakes are running about 1.25” long but with this type of preform I have and have seen pieces 4” wide cleared. The preform is designed so that the flake coming from the opposite side will overlap the first side making it look almost like one flake over the surface. This surface doesn’t need to be ground super smooth but depending on the availability of the knapper that is a personal choice. For me 80 grit is just fine but the ones I make to sell, we go to 220.
