The 18” Premier heavy-duty trimmer is an excellent paper trimmer suited to schools, churches and other businesses. It has a hardened steel, shelf-sharpening blade that is capable of cutting up to 20 sheets of 20lb paper at once as well as it can cut matte board, cardboard, film and tissue. A 3/4" wood base with a permanent 1/2" grid featuring Imperial and metric rulers help ensure proper alignment while cutting, and non-skid rubber feet help keep it steady. The paper trimmer has a soft-grip ergonomic handle for easy-grip cutting. Safety is a key feature of the 18” Premier heavy-duty trimmer as it has a patented automatic blade latch locks with every cutting motion, a finger guard runs the entire length of the blade and a torsion spring stops the blade from falling during operation. This paper trimmer is ideal for cutting your documents, cards and other printed media up to 18” wide.
