This 1931 jujitsu demonstration in Germany aimed to show how a well-trained unarmed woman could defend herself against a would-be attacker. In this scenario, a rope tied across the road has caused her to stop her car and she is set upon by a man with a knife. She controls the knife hand and engages the assailant by grabbing his throat before taking him to the floor with a throw.
