A cardboard cutter is a specialized hand tool designed to slice through heavy-duty paper products and corrugated fiberboard with precision and safety. Unlike a standard utility knife, many modern cardboard cutters feature recessed blades or shrouded tips to prevent accidental skin contact and protect the contents inside a package. They typically utilize high-carbon steel or ceramic blades that maintain a sharp edge through repetitive use, paired with an ergonomic handle to reduce hand fatigue during high-volume tasks like unboxing shipments or recycling.
