Designed to hold up to rigorous activity, day in and day out. The machine-ground, lever-style blade is sharp and accurate enough that it can remove even the tiniest sliver of paper from your work. For safety, a spring-action handle prevents the blade from falling down unexpectedly. Lightweight and marked with guides, Vantage® trimmers offer safety and convenience, while giving you the accuracy you require. To ensure an even cut, each trimmer features an automatic clamp that provides firm, even pressure, preventing paper from shifting. To protect the blade and keep fingers safe, the handle can be locked in the down position. For durability, the sturdy metal base provides a solid foundation. For measuring, the base contains carefully screened guides and an adjustable backstop -- which is the easiest way to ensure accuracy during repetitive cuts. And for portability, it's designed to be light enough to take anywhere.
