Knapping a Flint Knife — Stone Age Cutting Tool

Flint knapping: 2 million years old, still sharper than surgical steel. Learn percussion flaking to produce a usable knife from stone. Safety: wear eye protection and gloves.

Advanced
1-2 hours

Instructions

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.

Design

Diagram: striking angle, platform edge, flake removal direction
3

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.
4

Refine Edge

Switch to antler or hardwood baton. Lighter strikes, thinner flakes. Work along the cutting edge for a straight, sharp line.
5

Haft (Optional)

Split a wooden handle, insert blade, bind with cordage and pine pitch glue.
