Abstract

Tree felling wedges (10) of the type which are conical and on the cone's outer cover are fitted with threads (20, 22) so that they can be screwed into and can widen a saw cut in a tree trunk. The threaded part (20, 22) of the wedge is interrupted in at least one area with a smooth surface to reduce the friction between the thread and the tree trunk.<IMAGE>
