Copper Nail (13A126b, c)

A square shank copper nail, with a chisel point. According to Henry Mercer, a 'chisel' point is characterized by the tapering of the shank to a point on two opposite sides, and to a flat on the other two. It is used in shipbuilding so as to be driven safely into wood that may be more prone to splitting. Its curved shape suggests that it may have been 'clenched' in order to better grip the wood after being driven through the planking (1).

All artefacts appear to have come from a vessel of the Royal Navy.
