The root wacker tool is a manually operated hand tool that includes a shaft of which mounted thereon is a hammer cap for imparting a force into a blade located about an opposite end of the shaft, which is useful in the cutting of roots or stumps located within compacted soil. The slide hammer has a mushroom shape to form a finger guard, and can be disengaged from the shaft to connect to a handle accessory to form a sledge hammer. The handle accessory can be connected to the shaft for use as a root whacker tool or attached to the blade to form an ax. An accessory saw can be stored within the shaft when not in use, and can be attached to the handle accessory for use as a saw. The shaft is aligned above the desired cutting surface via a slide hammer that slides vertically about the shaft, and a footplate, which secures the blade with respect to the shaft.
