ABSTRACT:
The disclosed invention is a method and device for removing dirt and other debris from an open trench. The invention includes a tool with an elongated handle and a blade attached thereto. The blade is cantilevered from the support to allow positioning of dirt and other debris thereon. The combination creates an elongated shovel with a substantially flat bottom edge, so as to conform to the bottom of the trench. The handle and blade make a slightly acute angle one to another, with the center of gravity of the combination being below the handle when the handle is in a substantially vertical position and the placement of debris on the blade making little if any movement of that center of gravity. This method allows the user to stand directly over an open trench and remove soil with the tool with minimal displacement of the weight of the combination from the body of the user. This minimal displacement results in minimizing lower back stress while performing the task. Refilling of the trench is also assisted by allowing the user to be in an upright position with the blade of the tool flat on the ground and push or pull the soil back into the trench, without lifting the soil or putting the user in an awkward position.
