ABSTRACT OF THE DISCLOSURE A nail holder and a nail set holder used, in turn, to facilitate driving and setting, respectively, a finish nail, each having a resilient body with a truncated conical projection, an upper surface for receiving the impact force from a hammer blow, a lower surface of the projection adapted for bearing engagement with the workpiece, and an elongate axial hole extending therethrough for holding the element. The resilient body is compressed by the force of the flow received by the upper surface thereof and resiliently opposed the impact force with increased resilient force during increased compression to effectively limit the travel of the hammer, thus preventing overdriving of the element. The resilient body also shields the workpiece from the hammer. A flexible blade attached to the projection facilitates employment of the tool in otherwise inaccessible areas. In the nail holder, the resilient opposing force is applied to the hammer directly through engagement of the upper surface with the hammer head. In the nail set holder, the opposing force is transmitted to the hammer through a specially designed nail set element having a shank extending through the hole, a boss overlying the upper surface of the body, and a head for receiving the hammer blow.
