Plastic board and cutting mat: A cutting mat is placed or secured on a plastic board to create a stable surface for cutting tasks. Ruler with holes for the blade: A ruler (or a tool acting as a slider) with thin holes that allow the blade to pass through is secured on top of the plastic board. Left and right movement: A fixing device is used to allow 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, enabling it to be raised or lowered when needed. This seems to facilitate easy movement of the ruler and carrying out cutting tasks.
