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.
