Folding Utility Knives

The blade of a folding utility knife is tucked into the handle for secure transportation and storage. Only one corner of the blade is exposed during usage, so the blade can be changed to the new cutting edge when the first one dulls. Pull cuts are made using utility knives that have short, disposable blades attached to the handle. They cut cardboard, plastic sheeting, card stock, wire, and other materials, as well as score drywall and insulation.
