To open a bookbinding screw, you can use a screwdriver to turn the screw counterclockwise. As you turn the screw, the two parts of the screw will start to separate, allowing you to insert or remove the pages of the book. Once you have finished adding or removing pages, you can then use the screwdriver to tighten the screw by turning it clockwise, securing the pages in place. It's important to be gentle and not over-tighten the screw to avoid damaging the pages or the screw itself. **
