I don't remember what plug I have but it has a horizontal spade & a vertical spade with the ground between. No twist lock for me. If it can't come out of the plug-in the plug-in can be broken not to mention me falling flat on my face.
When I replace the factory cord I install a 15' cord 2-12 with ground.
