An apparatus for splitting materials including wood, having rotating conical wedge elements which screw their way into the material thereby splitting and/or fracturing the material. The axes of rotation of the conical wedge members are closer together at the pointed ends than at the base ends, and in a preferred embodiment are touching at the pointed ends with the surfaces of the conical wedge members in contact along their lengths.
