Description: | Greenstone or epidiorite adze, tear-shaped in plan and plano-convex in profile and section. The distinct curvature of one side of the blade, while the other side is flat, suggests that the implement was used as an adze, for woodworking, rather than an axe.The greenstone is thermally metamorphosed from an aureole of Lands End granite, and has been used as it was formed rather than pecked and ground into shape, apart from the blade end which has been worked. The butt end has a granite vein running through it which stands proud of the greenstone which has recrystalised on either side of the vein as the granite heated up the greenstone around it (Roger Taylor pers comm).A similar example has been excavated from the Neolithic settlement at Carn Brea and is illustrated in Mercer (1981) on page 155, Fig.64, No.S6.
