Plastic Board and Cutting Mat: A cutting mat is fitted or secured onto the plastic board to create a stable surface for cutting tasks. Ruler with slots for the knife: A ruler with thin slots that allow the knife to fit is secured onto the plastic board (or a tool that acts as a slider). Left and Right Movement: A fixing device allows the ruler to move left and right, enabling it to be positioned as desired during work. Up and Down Movement Using Springs: Springs are attached to allow the ruler to move up and down, making it possible to lift or lower the ruler as needed. This seems to facilitate easy movement of the ruler and efficient cutting tasks.
