The hand tool (10) comprises a tool part (1), which is retained in a preferably hollow cylindrical housing body (21) of a housing part (2) and which comprises an ultrasonic transducer (15), which has at least one piezoelectric element (154) and which is used to output ultrasound energy to a blade (11) provided on the tool part (1). According to the invention, a plurality of piezoelectric elements (154) separated from each other by contact elements (155) are provided, which piezoelectric elements each have a transfer opening (1541), through which a transducer rod (151) is fed, which is connected integrally or directly or indirectly to a coupling rod (12), which is connected integrally to the blade (11), and a pressing element (152) connected to the transducer rod (151) is provided, which pressing element presses the piezoelectric elements (154) against a stop surface (A) of an element connected directly or indirectly to the coupling rod (12) and mechanically couples the piezoelectric elements to the coupling rod (12). |
