Abstract

A pair of shear blades and a blowout preventer having the pair of shear blades. The shear blades are configured to cut a tubular Inside the blowout preventer. The shear blades have different geometries of the front cutting surfaces. One geometry promotes a secure positioning of the tubular relative to the first blade while the second geometry promotes a puncturing of the tubular by the second blade.
