Dahle’s Professional Paper Trimmers are perfect for all of your studio and office projects. The automatic paper clamp and adjustable back stop ensure accurate trimming every time. The ground steel, self-sharpening blade slices in both directions and creates burr-free cuts on as many as 20 sheets at a time. A plastic safety shield covers the blade and protects your fingers from injury. The sturdy metal base features pre-printed grid lines and is easily mounted on a wall.
