Abstract
A mechanical perforator with guide skates includes a perforator module and a skate module. The perforator module has perforator blades that may be forced outwardly to perforate machined-away areas of a well casing after the skate module has guided the perforator blades into alignment with the respective machined-away areas and locked the perforator blades in that alignment.
