Testing the efficiency of Bronze Age axes: An interdisciplinary experiment.

This paper discusses an interdisciplinary research project testing the efficiency of European Bronze Age axes through experiments with replica tools and the usewear analysis of prehistoric axe-heads from the collections of the Great North Museum, Newcastle upon Tyne (UK). The project explores whether changes in axe-head design and hafting arrangement from early to late Bronze Age might have been motivated by a desire to improve tool efficiency. The team, comprising researchers with backgrounds in archaeology, engineering, and statistical data modelling, carried out several field and laboratory tests to address the research problem. They subsequently validated the test results through the microscopic analysis of original Bronze Age axe-heads. The data suggest that hafting technology, and especially the resilience of the haft-blade assembly, is more important than axe-head design per se in determining the efficiency and working performance of Bronze Age axes. The research provides a fresh answer to a question rooted in 19th century archaeology and charts an innovative multidisciplinary pathway for studying human technology through the ages. • Axes changed their head designs and hafting technologies throughout the Bronze Age. • The resilience of the haft-blade assembly is more important than axe-head design per se in determining axe efficiency. • Experimental archaeology, usewear analysis, and tribology can be used to test the working parameters of ancient tools. • Statistical methods can be used to validate the results of these tests.
