Part 2 shows how to make a Blade Core preform using just a hammerstone. The finished preform is ready to remove pressure blades using a crutch. This type of core preform is similar to those found in Meso American blade core workshops and are believed to have been made at the quarry sites and then transported to the workshops. In Part 3 of this series we will begin removing pressure blades using an antler tipped chest crutch producing fine pressure blades.
