Abstract
An apparatus for marking and scoring sheet material having a side edge includes a base having an upper surface and a contact edge adapted to engage a side edge of the sheet material. A trans-base is secured perpendicularly to the base and is adapted to rest on the upper surface of the sheet material. The base and the trans-base are susceptible to rocking movement about a fulcrum defined by the trans-base as the contact edge of the base is drawn along the side edge of the sheet material. Stabilizing wing structure on the base is constructed and arranged to prevent any such rocking movement of the base and the trans-base as the contact edge is drawn along the side edge of the sheet material. The stabilizing wing structure includes an upturned side edge maintained out of engagement with the sheet material upper surface, to prevent the wing structure from engaging irregularities in the sheet material upper surface as the base contact edge is drawn along the sheet material side edge.
