https://primitivepathways.com Learn how to use lapidary saws and diamond grinders to make ultra-fine arrowheads. No these tools weren't available in prehistory, but their use can greatly reduce stone waste and maximize the amount of points you can make out of rare, semi-precious (and expensive) stone like agate or jaspers that are exotic or limited. Billy Berger shows how to use a small lapidary saw and diamond grinder to shape arrowhead blanks. The perfectly smooth and slightly rounded surfaces allow for beautifully even flake scars that resemble ripples of sand. These parallel pressure flakes give the arrowheads a beautiful, pleasing surface appearance. This can be used on all knappable materials like glass, obsidian, jasper, agate, flint, chert, and chalcedony among others.
