Abstract: A firewood splitting wedge tool for splitting quarters at one time from a log. The tool is formed integrally of metal with a cross-shaped cross section formed by four wedge blades each having the same wedge taper extending from a flat cross-shaped top surface downward to sharp lower blade edges. The blade edges are tapered slightly outwardly downwardly from the axial central body portion of the tool where the four blades join located at 90.degree. angles between each blade and its adjacent blades. The arrangement provides two primary coplanar blades and two secondary coplanar blades located normal to the primary coplanar blades, the latter being longer than the secondary coplanar blades. A wide flat curved sharp edged starter portion extends downwardly from the sharp angled lower ends of the primary blades.
