This is a heavier 12×12 trimmer by Making Memories.  It comes with a magnetic ruler that stores underneath.  The best feature to this is that the blade is self-sharpening so there are no replacement parts.  It has a rotary blade and cuts beautifully straight and sharp every time.  This is the most exact cutting trimmer I have ever owned.  Although it does take up a fair amount of space, I have made room for it on my desk because I love it so much.  You can fold it in half to take to crops or so it fits in a smaller space.  Down sides to this trimmer are that you cannot cut chipboard or more than 2 sheets of heavy cardstock at a time.  You can also not cut small pieces of paper (ex. 1″ x 1″) because of the guard that the paper slides underneath.  You can cut 1″ off a 12″ sheet of paper but once it is 2″, it is difficult to cut in half.  This is my favorite cutter and I would not want to be without it, however if you are looking for an all-in-one tool this is not it.  I use this cutter every time I scrapbook but I also use other trimmers to cut smaller pieces of paper.
