ABSTRACT OF THE DISCLOSURE A method for cutting and splitting tree trunks, preferably into firewood, and an apparatus for implementing the method wherein both the cutting and the splitting are carried out in the same operation. One end of a tree trunk is placed on a foundation below two vertically-disposed knives, one of which extends across the width of the tree trunk and the other longitudinally along a portion of the length to be split. The knives are mounted to move downwardly toward the foundation and upwardly away therefrom. On the downward movement one knife cuts a log from the end of the tree trunk and in the same operation the other knife splits the log longitudinally. The knives are then moved upwardly and the remaining tree trunk is moved longitudinally endwise placing another end portion below the knives. The sequence is repeated until the log is cut up into split firewood. At least one knife member is guided as it is driven downwardly toward and through the tree trunk.
