A hawk having a first board with an upper surface, an opposing lower surface, and an edge. A handle is attached to the lower surface of the first board, and a hinge is attached to the edge of the first board. A second board with an upper surface is also attached to the hinge. An angle between the first board and the second board can be set as desired by selectively rotating the hinge between the first board and the second board.
