A magnetic nail holder is an engineering control that can help reduce struck-by injuries because it provides a striking barrier that covers the fingers while the nail is positioned and hammered.  The holder is a clam-shell like device that has finger loops to grip and close the device.  It also contains an elastic band that helps keep it open into its resting position.  While the nail is loaded in its resting position, the nail is magnetically held in place.

A magnetic nail holder, such as the Safety Nailer, supports nails that are at least 1.5-inche long and has a 0.2-inch diameter magnetic opening that can secure up to a size 20D nail (figure 1).  It can also hold staples (figure 2) and screws (figure 3).  The device is made from impact-resistance ABS plastic and neodymium magnets.
