Abstract: A self-defense whip having an elongated hollow tube within which is telescopically received a flexible lash, preferably formed of flexible control cable. The tube has a constriction proximate one end and the lash has an anchor at one end which is axially movable in the tube but which will not pass through the constriction. The lash has a weighted tip at its other end which pulls the lash into extended whipping position and accelerates the tip into an arc leading the lash. When the lash is formed of flexible control cable, the whip makes an intimidating, whistling noise as it cuts through the air.
