Guillotine trimmer features a machine-ground blade that can remove the tiniest sliver of paper from your work for extremely precise cuts. To ensure an even cut the trimmer's automatic clamp provides firm even pressure to prevent paper shift. It cuts up to 15 sheets of paper at a time and includes a sturdy metal base with alignment guides for easy trimming. To protect the blade and keep fingers safe a spring-action handle prevents the blade from falling down unexpectedly. The handle can be safely secured in the down position. For stability the sturdy metal base provides a solid foundation. It's designed to hold up to rigorous activity day in and day out. The base includes carefully screened measurement guides and an adjustable backstop to ensure accuracy during repetitive cuts. Trimmer with a 12" cut length is perfect for cutting paper cardstock photo paper and more.
