Raw obsidian and a finished projectile point. Obsidian is a multi purpose material. From one good corestone, a variety of different tools can be created. Stone blades on antler or wood handles, attached by sinew. When a blade becomes dulled from excessive use, the edge can be dressed up by pressure flaking.
Pressure flaking creates the finely serated edges found on all sorts of stone tools.
An assortment of tools made from deer antlers. Antlers are used either as hammers of pressure flaking tools. The pointed tip of an antler tine, against the edge of obsidian, works well to pop off tiny chips, as in the serated edge of an arrowhead or spearpoint. The blunt end of a tine, might be well suited for heavier duty pressure flaking, or it even be used as a hammer to strike of flakes. Other materials, such as bone, or wood can also be used, but antler is said to work the best.
