     a pickaxe or pick is a hand tool with a hard head attached perpendicular to the handle. some people make the distinction that a pickaxe has a head with a pointed end and a blunt end, and a pick has both ends pointed, or only one end; but the international oxford dictionary of english states that both words mean the same, i.e. a tool with a long handle at right angles to a curved iron or steel bar with a point at one end and a chisel or point at the other, used for breaking up hard ground or rock.soanes, catherine and stevenson, angus (ed.)
