A paired set of handles attaching to a board forming a concrete screed to minimize the strain on a person performing concrete finishing work allows for an ergonomic application of downward force applied to the lower end of the handles and application of an upward lifting force by the shape of the grip portion at the upper end of the handles, with the shape and contour of the handles requiring less strain and strength than current screed handles.
