the Rape-aXe was originally called RapeX but was renamed in 2006 because RAPEX is also a European Union warning system for dangerous goods.
Ehlers mentioned that she was inspired to create the device when a patient who had been raped stated, "If only I had teeth down there."
It is equipped with teeth, sharp as razor blades, which will grip painfully to the penis of the rapist from the first attempt at penetration.
