Abstract: Cutting structure for scoring or cutting surfaces is disclosed. The cutting structure includes a housing having elongated sides, a blade and thumb positioning structure associated with the elongated sides. Measurement means may be positioned against the thumb positioning structure and may be held in place by the user's thumb thus providing a measured distance which may be cut. The invention further includes angled structure associated with the housing which provides a guiding surface when making angled or mitered cuts along the edge of drywall. The invention may also include a retractable measuring structure retained within the housing, a retractable blade, retaining means formed in the housing for housing spare blades and a notch for cutting rope and the like.
