Abstract: A hand-held tool comprises a tool part and a handle surrounding a section of the tool part and connected to same in a torque-transmitting manner. The tool part comprises a connection contour used to connect the handle in a torque-transmitting manner at least in some areas, in a section surrounded by the handle. The handle comprises an inner handle piece which can be connected to the connection contour and surrounds same in a torque-transmitting manner. With the inner handle piece slid onto the connection contour, one or more outwardly-open casting channels are provided between the two parts. The handle further comprises an outer handle piece made of plastic, which during the course of a plastic moulding process is moulded around the unit comprising the tool part which has an inner handle piece connected to the connection contour thereof, wherein the at least one casting channel is at least partially filled with the plastic material which forms the outer handle piece. A method is also described for producing such a hand-held tool.
