According to one aspect of the application, a tool for driving a fastening element into an underlying surface comprises an energy transmission element for transmitting energy to the fastening element. The energy transmission element is preferably movable between an initial position and a setting position, the energy transmission device being in the initial position before the driving process and in the setting position after the driving process.According to another aspect of the application, the tool comprises a mechanical energy accumulator for storing mechanical energy. The energy transmission element is then suitable particularly for transmitting energy from the mechanical energy accumulator to the fastening element.
