Tips & Techniques » Choosing The Right Paper Trimmer Let’s take a look at some of the differences and strengths between the Rotary Trimmer and the Guillotine Trimmer. When choosing a trimmer, you will need to take a look at what kind of jobs you will be using it for. 1. The Number of Pages to be Cut at the Same Time: If you consistently need 20 pages cut, don’t make 20 separate, individual cuts. By making a single cut, you save time and labor. You also ensure that each piece is cut uniformly and accurately. Guillotine Trimmers are best suited for larger paper stacks and/or heavier materials. They utilize a carbon steel blade with a handle to give the operator plenty of leverage with which to cut. Features include an automatic paper clamp, blade lock, safety guard, and printed grid guides on a rugged steel base. Guillotine Trimmer blades are self-sharpening which allows for long-term use without the need for replacement. 2. Paper Size to be Trimmed: If you need a cutter with the largest cutting surface, a Rotary Trimmer may be just the thing. Rotary Trimmers use a self-sharpening circular blade, housed in a rugged, ergonomic cutting head which allows for safe cutting in two directions. Rotary Trimmers can accommodate larger sheet sizes, up to 51” long, and feature printed grid guides. Larger models include a rugged steel stand and fabric catch tray for trimmed scraps.
