Scrib′ing-com′pass.
(Saddlery.) A compass with one pointed leg to act as a pivot, and one scooping edge to act as a marker. It is especially used to remove the gum on patent leather in a line for a row of stitches, and is set open to any degree by the arc and set-screw. It is also used as a scribe in making a line near the edge of a strap, one leg passing along the guideedge, while the other makes a groove on the line required.
