ABSTRACT:
A pipe notching tool to produce a notch extending longitudinally of the pipe from an end thereof, the tool including two members pivotally interconnected, one member having a slotted die part and the other member having a blade which can be inserted in the die part as a result of relative pivotal motion between the members. The blade has a curved cutting edge which produces a continuing shear as the blade is inserted into the die so as to reduce the amount of effort required to complete the notching operation.
