    Abstract: A wood splitter (1) comprises a splitting wedge (2), a guide bar (3) connected to it at the back (2a) of the splitting wedge (2), and a drop weight (4) movable along the guide bar (3) and encircling the guide bar (3) in cross section. The guide bar (3) is provided with an external thread (3a) at its end area facing the splitting wedge (2) and is screwed into a threaded bore (2b) sunk into the wedge back (2a). There is an intermediate plastic sleeve (5) between the drop weight (4) and the splitting wedge (2), with the longitudinal axis (L) of the guide bar (3) running perpendicularly to the opposing faces (5b, 2b) of the intermediate sleeve (5) and the back (2a) of the wedge. These measures provide a wood splitter (1) with which the risk of damaging the junction between the splitting wedge (2) and the guide bar (3) is distinctly reduced, even with large drop weights (4) and corresponding impact forces.
