Initially, jointing was performed with a jointer plane but nowadays, jointer machines, hand held routers, straight edge, or table-mounted router are employed; this joint occurs when an edge of a wood board is straight along its length and perpendicular to the face of the board; when panels are glued up and the edge is slightly concave along its length, the result is referred to as a sprung joint; when the two edges are secured and clamped, the sprung edges create greater tension at the join ends, helping in the production a seamless joint; when a hand plane is employed, two boards are often clamped face to face in the vice and both jointed simultaneously, producing two edges that are the mirror image of each other; even if the edges are not absolutely perpendicular to their respective faces, when the two board edges are secured, the result is a flat panel because the error in one edge cancels out the error in the other
