A hand tool having a flat, planar blade parallel to a surface and a variable length handle allows efficient and effective grading or leveling of a surface. The device allows for effective grading without undue stress on the body of the operator. The ergonomic design of the device, as well as the functional design, allow for effective and efficient grading of surfaces next to and surrounding sensitive structures.
