1. A cutting device comprising:
a round of shots operable to perforate through a wellbore conduit to sever one or more control lines, each of the round of shots having a radial shape such that each of the round of shots perforates the wellbore conduit along an apex angle,
wherein each shot of the round of shots overlaps an adjacent shot in the round of shots by an overlap width that is equal to or greater than a line width of the one or more control lines so that any combination of the shot and/or the adjacent shot fully severs the one or more control lines, and
wherein an apex angle for each shot of the round of shots overlaps an apex angle for the adjacent shot by an overlap angle of at least about 28 degrees so that the shot overlaps the adjacent shot by the overlap width.
