Finally, a paper cutter that will cut at very nearly a perfect right-angle when paper is lined up with the top paper guide. I've purchased many other paper cutters over the years of all prices and styles and this is the first that has come this close. The wire is a great aid for lining up pre-measured and marked paper. The increments marked on the face of the cutter and running the length of the cutting bed facilitate cutting to the closest 1/4" while the rulers at the top and bottom will enable 1/16" measurements. The blade tracks well without the blade guides distorting under pressure. The 8-1/2" x 12-1/2" cutting bed is just right for cutting 12" scrapbook paper yet the overall 8-1/2" x 14-1/2" size of the cutter makes it small enough to travel with ease. A well-thought-out tool. Two thumbs up for this priced-right cutter.
