Plastic board and cutting mat: Place or secure the cutting mat on the plastic board to create a stable surface for cutting tasks. Ruler with holes for the knife: Secure a ruler (or a tool that functions as a slider) with thin holes on the plastic board that allows a knife to fit through. Left and right movement: Use a fastening device so that the ruler can move left and right, allowing you to position it as desired during work. Up and down movement using springs: Attach springs to allow the ruler to move up and down, enabling you to lift or lower it as needed. This should make it easier to maneuver the ruler and carry out cutting tasks with a utility knife.
