The Dual-Purpose Carpet & Utility Knife is manufactured to cut using either a carpet or a utility blade, according to need. Its patent-pending design features a thumbscrew for fast, tool-free blade change and a plastic insert holds the blade in place, positioning it on the left for carpet blades and on the right side for utility blades. This is a lightweight knife for easy maneuvering while cutting, without weighing the hand down. It has a contoured handle for a comfortable grip, and on-board storage for replacement blades in the handle.
