Beyond direct pressure, what subtle manipulation of a pen as a pressure point weapon can dramatically amplify its impact on a sensitive nerve cluster?

Beyond direct pressure, a subtle manipulation of a pen as a pressure point weapon that can dramatically amplify its impact on a sensitive nerve cluster is applying a 'small, rapid circular motion' while maintaining pressure. This circular motion, often described as a 'grinding' action, stimulates the nerve endings more intensely and disrupts the pain signals more effectively than simple sustained pressure. This technique maximizes the discomfort and disorientation caused by the pressure point application, even with relatively light pressure, making it significantly more effective for gaining compliance or creating an opening for escape.
