This small cutter is perfect for cutting perforation lines into paper, film, and other materials for easy tearing. Run the cutter over the page of a notebook or magazine to make it easy to tear out pages in a clean line. Unlike a traditional paper cutter, if you make a perforation line over the wrong area, the paper will remain in place as long as you do not pull it apart — not to mention the extra charm from personalizing your paper with the extra optional step instead of cutting it directly.
