Abstract
An ergonomic counter-balanced handled tool that is ergonomic and counter-balanced includes a tube that is angled proximate to a midpoint of the tube defining a lower section and an upper section of the tube. The lower section extends transversely from the upper section. A counterweight is slidably coupled to the upper section proximate to a first end of the tube. The counterweight is positionable at a user-selected distance from the first end. A tool is reversibly couplable to a second end of the tube. A harness is couplable to the upper section of the tube, such that the harness is configured to position around a user'"'"'s shoulder. The counterweight is positioned to extend from the first end of the tube such that the tool and a respective load positioned at the second end are substantially balanced relative to the harness.
