Abstract
The anti-splitting device of the present invention has a central-web portion and a pair of end web portions, which are joined adjacent to their midpoints to opposite ends of the central web portion to provide the device with generally I-shaped cross-sectional configurations. The web portions have first side edges tapered to define a cutting edge and second side edges serving to define a planar driven surface disposed parallel to the cutting edge. And on the central web portion are at least two projections to upstand from driven surface. The projections are adapted to removably attach the device to a driver employed to insert the device into a log. The driver of the present invention is preferably in the form of a manually operational hammer having a planar driver surface of circular plan form configuration and a circular groove that has an outer diameter equidistant and an inner diameter equidistant from a given fixed point, the center of the planar driving surface. The groove receives the projections and contacts a predetermined portion of the projections; the projections exert a force on either the outer diameter or the inner diameter, and do not contact both diameters at the same time. The device can then be freely rotated in the groove to obtain a desired position on the driver surface.
