I am going to buy a paper trimmer. However I have a couple of small concerns regarding the size. I have my eye on one which has a 11.5 x 15 inch base and a 12 inch cut I would be guessing right in guessing that this cutter can cut 8.5 x 11 paper to 8x10? Correct? If not could someone give me the dimensions on a cutter that I should be using. Please respond asap.
