You're staring at a stack of card stock or a length of duct tape and the blade in your hand is already dull. You don't need another flimsy tool that bends on the second cut. The Marbig Large Utility Knife gives you an 18mm blade that slices through paper, light plastic, and craft material without tearing. Polystyrene grip means it sits steady in your hand even when you're cutting for twenty minutes straight in a classroom or at a kitchen table. One tool, one job done clean, no hunting for a second blade halfway through the lesson
