Mueller-Kueps introduced the Pro-Xnife Kit, No. 268 500. The Pro-Xnife Kit features three different blade types to provide users with a universal use kit. The Pro-Xnife is designed for cutting coolant hoses, zip ties, carpet, wire harnesses, plastic, door panels, and more. A two-component handle with rubber grip allows users to use the knife without worrying about it slipping out of hand. Designed to be used with a pulling motion, the knife stays sharp longer than an average utility knife, the company says.
