In one aspect of the invention, a tool comprises a head and a shank assembly. The shank assembly has a tensioned element axially disposed within a bore of a structural element and a distal end of the tensioned element is secured within or below the bore. The head has a cavity formed in its base end and is adapted to receive a proximal end of the tensioned element. The tensioned element has a radially extending catch adapted to interlock within the cavity of the head. The head is harder than the tensioned element.
