Abstract: A hand-operated, reciprocating slide hammer device for splitting wood or other workpieces. The splitter comprises an outer, elongated sleeve that internally receives a rigid, elongated tool control shaft. The sleeve is equipped with handles for gripping by a user so it may be first manually lifted upwardly and then forcibly drawn downwardly. An internal weight coaxially disposed at the sleeve top periodically slams the shaft when the sleeve is hammered downwardly. Alternate cutting tools including wedges, a root cutter, and an asphalt hammer, are disclosed. The selected tool is removably coupled to the shaft through a quick release collar system. The selected tool is manually placed in engagement with the workpiece, and thereafter pounded into the target as the sleeve vigorously hammers the shaft downwardly. Smooth, jam-free operation is insured by critical alignment guides disposed within an annulus between the shaft and the sleeve, and a venting orifice that facilitates periodic oiling.
