Abstract
A two-pointed nail driver system is provided for joining materials, such as planks together. The system consists of a column or sleeve used as a hammer. This column or sleeve is provided with a bore extending longitudinally lengthwise from one end of the column or sleeve but terminating short of the opposite end of the column or sleeve. A plunger element is positioned in the bore and its length extends beyond the bore and externally of the column and/or sleeve. At least one aperture is provided in the plunger element and extends lengthwise and longitudinally thereof. This aperture is arranged to receive one end of a two pointed nail having a head intermediate the ends of the two pointed nail and adjacent to the opening of the aperture. When the two-pointed nail is properly positioned, the column or sleeve can be used to strike the plunger to drive one end of the nail into a first member which is to be joined to a second member, such as planks.
