During Quartermaine & Claris's 1986 survey of the Langdale axe factories they looked at the south scree on the Pike of Sickle. By measuring the rock density and proportion of worked to unworked materials and then working on a principle derived from practicle experiments that each roughout weighing 1kg would produce waste flakes of between 6 & 10kg they concluded that between 45,000 and 75,000 axes were produced from this area alone. Taking into account other factories around Cumbria, the production figures are huge.
This is an industrial process and would have required a huge workforce.
Of course no two axes are identical as each axe was quarried prepared flaked & polished by hand.
There are axes that appear to have non-functional purposes such as the beautiful polished Jadite axes. Richard Bradley has identified that the axes from the most inaccessible peaks held the highest value.
