A tool for cutting tubing or light pipe provides conventional cutting rollers and a blade in combination with a spring loaded, open jaw clamp. The open jaw permits the tool to be passed over the side of the material to be cut, while the spring compressive force automatically urges the cutting blade into the material being cut as the tool is rotated around the material in the manner of conventional tubing and pipe cutters. Thus, the need to continually adjust the cutting blade as the cut deepens is eliminated. Two basic embodiments are disclosed, one comprising a handled clamp type tool with or without foldable or extendible handles, and the other comprising a C clamp type tool. The spring loading arrangement of the cutting blade is common to both. Various versions and improvements are also disclosed, including mechanisms providing for parallel actuation of the cutting assembly, proper spacing of the cutting rollers, and maintaining the proper angular relationship between the rollers and the cutting blade.
