Iron Age strike-a-light.
Palm-sized round brown pebble with deep straight grooves on both sides. An Iron Age multifunctional tool: the grooves were used as a ‘strike-a-light’, the edges for hammering, and the flat surfaces for rubbing hide. Found near the top of Dun Mor, Vaul, on 27th July 2005 by holiday-maker Kenny Nelson. It may also have been used by sail-makers for sharpening their needles.
