1

Select Stone

Flint, chert, or obsidian. Waxy luster, rings when tapped, no granular texture. Check riverbeds and limestone outcrops. Avoid cracked stones.
2

Platform & Primary Flaking

Strike off a small piece to create a flat platform. Hit 1cm from the edge with hammerstone — strike through the stone, not at it. Each flake creates a new platform.

Shape the Blade

Work around the nodule removing flakes to create a leaf shape. Alternate sides to thin evenly. Target: 10-15cm long, thin enough for a sharp edge.
