Abstract: A device for splitting a log of wood or other material comprising a pair of similar augers of generally conical configuration disposed on spaced parallel axes, preferably to rotate in opposite directions. The augers are mounted as a convenient, manually portable unit in operative relation with a suitable power source, speed reduction unit and clutch. The invention is considered especially suitable for home use, though it may be embodied in a gang of any desired number of augers for rail splitting or other application, for home or industrial use. In some instances, certain advantages of my invention may be had with the tandem augers rotating in the same direction.
