Rob Sands explores the evidence left by the use of axes on wooden beams and tools found in waterlogged archaeological sites dating over 2000 years old. A toolmark can not only inform the archaeologist about the implement used, but also provides evidence of building and artifact construction methods and labor patterns. Examples come from the author s work at Oakbank Crannog in Scotland. The volume examines the methods of recording, techniques of analysis and implications of this unusual form of evidence."
