Patent abstract

A folding ruler is provided. One embodiment of the folding ruler includes a first panel, a second panel, a hinge and a stiffening member. The first and second panels are interconnected end to end by the hinge so that the ruler can move between a folded state wherein the first and second panels are generally parallel and overlapping, and an unfolded state wherein the first and second panels are coplanar and oriented end to end. The stiffening member couples with the first and second panels to lock the first and second panels in the unfolded state. In some embodiments the stiffening member provides a grip for holding the ruler.
