Abstract: A mechanical assembly disposed on the back surface of a handheld electronic device, or a case for holding such a device, provides a pinky finger extension for an individual's hand to use an electronic device comfortably and with decreased possibility of dropping or damaging the electronic device. The pinky finger extension can be moved between a closed position, where it is inaccessible, and an open position where the user can place their fourth or pinky finger over the pinky finger extension.
