Flint seems to have been brought into areas of Britain where local resources are limited; the stone tools found in the caves of Devon, such as Kent's Cavern, seem to have been sourced from Salisbury Plain, one hundred miles (one hundred and sixty-one kilometers) east.

This is interpreted as meaning that the early inhabitants of Britain were highly mobile, roaming over wide distances and carrying 'toolkits' of flint blades with them rather than heavy, unworked flint nodules or improvising tools extemporaneously.

The possibility that groups also traveled to meet and exchange goods or sent out dedicated expeditions to source flint has also been suggested.
