Abstract

A cutter module includes a piston and a shear blade. The piston includes at least two movable telescoping elements that are adapted to expand from a first retracted length to a second expanded length. The shear blade is connected to the first piston to sever a tubing in response to the piston expanding from the retracted length to the second expanded length. The shear blade has a cutting edge that has a radius greater than 0.01 inches.
