Guillotine paper trimmers come in either wood or metal base. The base will either have its own clamp to secure the paper, or you will hold the paper in place while cutting. They also have an arm with a blade underneath and handle that you operate to cut the paper. This type of paper cutter is meant for occasional or low volume paper cutting- usually they can handle between 10 and 30 sheets of paper at a time.
All manual guillotine trimmers have a maximum length of paper they can cut. If you need to cut larger or varying lengths of paper, a rotary trimmer might be a better option.
Rotary trimmers are distinct from other trimmers in that they can cut greater lengths of paper and newer models offer a variety of cuts other than just straight lines. You have more control with a rotary trimmer because you slide a small, two sided blade up and down the length of paper to make cuts. High-quality rotary trimmers typically make cleaner cuts than guillotine trimmers, and come in manual or electric models for large volumes of preset cuts
Stack Paper Trimmers
Stack paper cutters can cut large stacks of paper or card stock - up to 750 sheets. They are similar to guillotines in that they have an arm that operates to cut the paper. With a manual stack cutter, the arm has a spring mechanism that provides the force to make cuts when you operate it. There are also electric stack paper cutters, which are made for higher volume use. They come either semi-automatic (with manual back gauge and clamp) or fully programmable focus group
