What is Knapped stone?

Flintknapping is the making of flaked or chipped stone tools. ... These rock types, when struck with another rock, piece of antler, or bone, will fracture or break in a characteristic pattern called a conchoidal fracture.

How can you tell if a flint has been Knapped?

Just below the point of percussion the fracture travels through the flint in a cone shape which quickly develops into a swelling, or bulb, and then diffuses out until it meets the edge of the core. The flake will therefore have a small cone-shaped feature and a swelling on its ventral face.
