Abstract
A hand tool for safely removing and installing the unitized jaw assembly in power sucker rod tongs has a tool head equipped with spring loaded paws for gripping the jaw assembly. A tool handle allows rotation of the tool head with the jaw assembly to protect the tool operator against injury when installing or removing the jaw assembly from the power tongs.
