Abstract: A personal safety device is provided to be held in a user's hand and to apply a striking force at an impact tip. The device includes a body defining a longitudinal axis, an upper end, and a lower end. An upper saddle may be provided to position the user's thumb over the upper end of the body. An index finger saddle may extend around the body adjacent the upper saddle to receive the index finger of the user's hand. A palm swell may curve outwardly from the body to fit into the user's palm. The body may be provided with smoothly curved contours between the saddles and the swell, so that the device is comfortably gripped and the striking force is spread throughout the user's hand. An alarm, strobe, camera, light, wireless transmitter, GPS device, fluid collection port, dye marker, straps, sheaths, and other defense and security features may be provided with the device.
