Abstract: A wire saw for cutting of stone is disclosed. Abrasive cutter elements are borne on slidable rotatable carriers encompassing a single filament metallic wire. The longitudinal motion of the slidable carrier elements is limited by helical spring restraining elements which are joined to the wire by a non-embrittling process leaving the rear end of the helical spring restraining element fixed to the wire but letting the front portion compress along the axis of the wire thereby absorbing shock imparted to the abrasive cutter elements upon impact with the stone.
