ABSTRACT:
A tool for cutting flexible plastic conduit having a pair of pivotally attached handles. One of the handles includes a cutting blade. The cutting blade cooperatively associates with an anvil located on the other handle. The cutting blade and anvil form a cutting jaw. The anvil includes at least one support to resist deformation of the flexible conduit during the cutting operation. The support is shaped to conform to a portion of the exterior profile of the flexible pipe being cut. A slot bisects the anvil such that the cutting blade can completely pass through the conduit and the supports.
