A manually guided implement possesses a guide tube, wherein a first mass body is disposed on a first end of the guide tube, and a second mass body is disposed on a second end of the guide tube. One of the mass bodies has a housing, and the other of the mass bodies has a tool driven by a drive motor. A power transmission mechanism for driving the tool between the first and second ends of the guide tube is guided in the interior of the guide tube. A first antivibration element is disposed between the first end of the guide tube and the first mass body. The guide tube in the direction of the longitudinal central axis thereof includes a first rigid sub-portion and a second rigid sub-portion that are connected to one another at an abutment location by at least one second antivibration element.

A telescopic drive shaft in a protective tube of a handheld work apparatus has one end connected to a rotational drive and the other end thereof to a driven tool. The drive shaft includes a rigid shaft segment and a connecting section. The rigid shaft segment has a hollow shaft end portion and an engagement length (E) of the connecting section engages therein. The engagement length (E) and the length of the hollow shaft end portion mutually overlap to form a joining section. The hollow shaft end portion is deformed for connecting the connecting section to the rigid shaft segment. The material of the hollow shaft end portion is compressed over its entire periphery and deformed so that the material of the hollow shaft end portion is radially displaced and is pressed in a rotative manner onto the engagement length (E) to produce a balanced, loadable connection.
