Blue Dog Square is a Fastcap layout tool designed to make scribing fast, accurate lines effortless on woodworking jobs. Its design focuses on eliminating awkward alignment, so you can concentrate on cutting and fitting instead of fighting your square. By using built-in arms with rotating dogs, the square locates the material edge for you, which reduces time spent measuring and rechecking. When the tool is set on a flat surface, the dogs retract into the square, so the reference face sits where you expect it and gives a consistent mark. The same dogs also let the square hang on vertical panels, providing a steady reference line without fumbling or tilting the tool during layout.
The Blue Dog Square uses its rotatable dogs to locate the edge of the workpiece, so the blade of the square stays correctly positioned while you scribe. Because the dogs retract on a flat surface, the square sits flush, letting your pencil follow a predictable path. Hanging the square on a vertical panel uses the same dogs as a support ledge, keeping the reference face steady while you transfer lines. This combination of edge finding and line referencing streamlines layout where panels are already standing or hard to reach.
The Blue Dog Square is built around the task of scribing fast, accurate lines on material edges and faces. Its five rotatable dogs along the arms pick up the edge regardless of material thickness, so a single setup works across different sheet goods or solid stock. On horizontal work, the retracting dogs allow the body of the square to sit flat, giving a reliable registration surface for your pencil or knife as you move along the edge. On vertical panels, the dogs act as a temporary ledge, letting the square hang while still referencing the panel face, which is useful when transferring heights or layout marks across a tall run.
The Blue Dog Square focuses on eliminating awkward alignment by combining edge location and line reference in a single motion. The rotatable dogs position themselves at the material edge, which sets the square in place without repeated nudging or visual guessing. When those dogs retract on a flat surface, the square maintains a stable, predictable bearing, helping your scribe line stay straight across the full reach. On vertical work, the same dogs support the tool as it hangs, preventing tilting while you mark, which can reduce marking errors and rework when fitting parts to existing panels or cases.
