The Durablade TM double bevel edge blades are precision engineered for maximum hardness and sharpness. The VC Series is a newly designed ratcheting rigid plastic pipe cutter that cuts straight and square every time with minimal force due to it's highly engineered multi ratchet stepping process. They also feature a quick release mechanism allowing the jaws to open without having to pull the handles apart. The only cutter of its kind that truly allows one handed operation.
