The Grace USA Original Gun Care Screwdriver Set is a true classic. This gun tool kit consists of 8 custom hollow-ground screwdrivers, made to fit all the small and irregular shaped screws that one encounters during gun maintenance, from scope screws to plug screws, guard screws, floor plate screws, sight screws and more. Still hand-assembled as it has been for decades, each screwdriver in the Grace Original Gun Care Screwdriver Kit has a turned Maine hardwood handle with a protective finish. The screwdriver blades are square-shanked and hardened and tempered to RC 52-56 standards, so they will not twist or chip. The Grace USA Original Gun Care Set is still an essential component of firearms maintenence!
