Abstract: An apparatus and method for a tool to mark a pitch or a cut line for treads and risers of a stairway, is disclosed herein. The tool includes a first member for marking a rise dimension; a second member for marking a run dimension, and a guide member for acting as a guide against a work piece, all coupled together using adjustable fasteners. The rise dimension and the run dimension are perpendicular to each other, thereby creating a pitch for stair cutouts on a stringer work piece or a pitch for a rafter rake. Individually, the first and second member are selectively adjustable with respect to the guide member to provide a wide range of rise and run dimensions, respectively, The first, second, and guide members can be loosened and repositioned to compactly stow as a composite shape for easy storage and transport.

Abstract: An apparatus and method for a hinged measuring and marking device is disclosed herein. The device utilizes a first member, containing a flat surface with a straightedge for marking or measuring, coupled to a second member, also containing a flat surface with a straightedge for measuring or marking wherein the first member is coupled to the second member in a direction perpendicular to the straightedge of the first member. The straightedges of the first and second members are coplanar for marking an approximately contiguous line on a single plane or on two intersecting planes. The first member and the second member can be rotated between 0 and 180 degrees with respect to each other to accommodate marking a line on the two intersecting planes.
