A 'cutting scoreboard' (or score board/trimmer) is a popular paper crafting tool that combines a paper trimmer and a scoring guide, used for making straight cuts and crisp folds for cards, envelopes, boxes, and scrapbooking, featuring measurement markings, a cutting blade, and a scoring tool for creating precise, professional-looking projects. Key Functions Scoring: Creates indented lines (creases) on cardstock for perfect folding without cracking. Cutting: Has a built-in blade or trimmer for straight, clean cuts. Folding/Creasing: Guides you to make envelopes, gift boxes, and intricate paper designs. How It Works (for scoring) Align your paper to the desired measurement on the board. Place the scoring tool (often a stylus or bone folder) in the groove. Pull the tool down the groove to create a valley fold line. Fold the paper along the line and burnish (press) it with a bone folder for a crisp finish.
