A blade beam of a motor driven hedge trimmer has two shearing knives. A shearing knife is movable in an oscillating manner through a stroke between two reversal points in the opposite direction with respect to the other shearing knife. Both shearing knives have spaced-apart cutting teeth that act against each other, and are at least partially provided with shearing blades for the chipless, shearing severing of material to be cut. A first cutting tooth of the one shearing knife lies at least partially in overlap with a first or second cutting tooth of the other shearing knife at the two reversal points. The blade beam has a trim cut region, in which the first cutting tooth of the one shearing knife completely glides, between its two reversal points, over a third cutting tooth lying between the first and the second cutting tooth of the other shearing knife.
