When it comes to wrapping presents, I need a paper cutter that's easier, faster and more accurate than scissors, like the cool new OpenX - Precision Wrapping Paper Slitter. For some reason, I seem to be incapable of cutting a straight line with scissors and the paper usually bunches up and tears. The OpenX eliminates the problem of bunching and tearing and easily slices through wrapping paper, mylar and more using a precision recessed blade crafted in Germany. It won't give you the same skills as those professional gift wrappers at the mall, but it will at least give you wrapping paper that's professionally cut straight.
