    Abstract: A handle fastening coupling, preferably for household and gardening implements comprises a guide piece (12) that is pressed into a handle-tube end and has an elongated guide channel (14) for a handle insert pin (3), which has a first end fastened to the implement and second free end, wherein the second end has a lock opening (6); and a locking element (20) that is preloaded by a latch spring (18) in a first radial direction perpendicular to the handle axis and that is designed to snap into the lock opening of the handle insert pin, wherein the locking element can be moved out of the lock opening in the radial direction by an operating button in order to release the handle insert pin (3) to pull it out of the guide channel, is characterized in that at least one pressure cam (7) that is elastically preloaded toward the inside in the radial direction is arranged adjacent to the lock opening (6) in the guide channel (14) of the guide piece (12), which is designed to exert radial forces at an angle to the first radial direction onto a handle insert pin (3) inserted into the guide channel (14).

    Abstract: A mower blade for a lawn maintenance device includes an elongate blade having opposed end edges and opposed side edges. The elongate blade is adapted for mounting onto a rotary mower for rotation about a center axis extended transverse to the elongate blade and separating the elongate blade into opposed elongate end portions extended from said center axis. The elongate blade has a blade major axis and defines a curved portion such that the curved portion is opposite a cutting edge. The curved portion extends from the elongate blade in an upward direction where the two meet and curves toward a lower face of the elongate blade. Further examples of the mower blade include the curved portion being offset vertically from a cutting edge to develop lift during rotation and a constant cross-section over most of the blade major axis.
