The Quick Change Utility Knife with a double soft grip, full metal ergonomic handle. The retractable knife is designed to make blade changes quick and easy. Just release and hold the button to swap in a new blade. The string cutter notch allows you to safely trim long strands of twine or wire down to size, and extra blades can be stored in a compartment inside the handle. The Quick Change Utility Knife includes 3 serrated utility blades, which feature multiple cutting edges to distribute friction, allowing each blade to cut faster and last longer than a traditional box cutter knife blade.
