Excavations at a suspected Iron Age site in Caithness, Scotland, resulted in a find of a whetstone, a tool used for sharpening metal objects.
Archaeologists believe that the site contains remains of an Iron Age home, called a wig. Construction of these type of structures began after a period of broch-building. Brochs were large stone towers and remains of them can be found across the Scottish Highlands and in the Northern Isles. The finely-grained whetstone has been taken to a University of the Highlands and Islands laboratory for further examination.
