Abstract:
An apparatus for marking and scoring sheet material having a side edge and a surface, comprising:a blade extending along a longitudinal axis and defining an inner end, an outer end, and an underside adapted to engage the surface of the sheet material, wherein the blade includes a series of spaced openings along its length outwardly of the inner end, and further includes one or more mounting apertures located toward the inner end;a base formed of a molded material and fixedly secured to the blade toward the inner end of the blade, wherein the material of the base is molded around the inner end of the blade and extends into and through the mounting apertures so as to fixedly secure the base to the blade, wherein the base defines a contact edge substantially perpendicular to the longitudinal axis of the blade;a pair of stabilizing members associated with the base and located one on either side of the blade, wherein each stabilizing member extends from the contact edge and defines a stabilizing surface substantially coplanar with the underside of the blade for providing stability to the apparatus when the contact edge of the base is engaged with the side edge of the sheet material and the underside of the blade is engaged with the surface of the sheet material, wherein each stabilizing member includes an upwardly extending side edge portion for facilitating movement of the base along the sheet material side edge without the stabilizing members engaging irregularities in the sheet material surface; andhandle structure provided on the base for manual engagement by a user for enabling the user to move the base along the side edge of the sheet material;wherein the openings in the blade are adapted to receive a tip of a marking or scoring instrument to provide a mark or a score on the surface of the sheet material as the base and blade are moved along the sheet material with the contact edge of the base in engagement with the side edge of the sheet material.
