The Shetland Knives are a collection of 18, beautifully honed and marked slivers of stone from Neolithic times. They had been buried in the peat earth and were discovered by chance. In some way, one knife had surfaced, like a ghost from the past. It was close to a little-used path across the peaty heathland. The rest were discovered buried in a kist close by. The 'breaking free of boundaries.' has been the theme of this ongoing series of work. No one really knows why they were buried there, or just how serendipity worked, to have one 'float' to the surface and be discovered in such an isolated place.
