Abstract
A blind shear ram includes an upper carrier including an upper blade and a lower carrier including a lower blade. The upper carrier and the lower carrier are positionable in a first position in which the upper carrier and the lower carrier are spaced apart and a second position in which the upper carrier and the lower carrier seal a wellbore. The upper blade and the lower blade are configured to cut at least one pipe and at least one cable when the upper carrier and the lower carrier move between the first position and the second position. At least one of the upper blade and the lower blade includes a textured surface configured to induce friction between the at least one cable and the blade.
