Hand shears, in particular pruning, hedge and/or garden shears, having two cutting elements (42, 52) pivotable about a first stationary hinge by two hand levers (41, 43, 49; 61, 63, 69), which cutting elements form a cutter head, comprising the following features: the first cutting element is arranged at an end of a first hand lever (41, 43, 49), whereas the second cutting element has a drive lever projecting beyond the first stationary hinge, an end of the second hand lever (61, 63, 69) is connected to the first hand lever (41, 43, 49) by a second stationary hinge, which is offset in parallel to the first hinge, an elongated coupler has third and fourth hinges (8, 9) on its ends, the third hinge of which being hinged at the free end of the drive lever at an axial distance from the first hinge and forming a first hinge pair (2, 8) with it, and the fourth hinge being hinged at an axial distance from the second hinge to the second hand lever (61, 63, 69) and forming a second hinge pair (3, 9) with it, the two hand levers (41, 43, 49; 61, 63, 69) and the two cutting elements (42, 52) form a four-hinge system formed by hinge bolts of the hinge pairs (2, 8; 3, 9), wherein the distance of the hinges of at least one of the hinge pairs (2, 8; 3, 9) is changeable in that the fourth hinge arranged on the second hand lever (61, 63, 69) is axially displaceable in a slotted link in the form of a slot guide within this lever between a first position for a normal cut and a second position for a power cut at an increased reduction ratio, and is resettable into the position corresponding to the normal cut by a first spring element, characterized in that a power cut latching device is provided, which after the hand levers (41, 43, 49; 61, 63, 69) have been moved apart completely, holds the displaceable hinge in a position corresponding to the power cut, and is releasable by merely moving the hand levers (41, 43, 49; 61, 63, 69) completely towards one another, so as to enable a return movement of the displaceable hinge by the first spring element into the position corresponding to the normal cut. the first cutting element is arranged at an end of a first hand lever (41, 43, 49), whereas the second cutting element has a drive lever projecting beyond the first stationary hinge, an end of the second hand lever (61, 63, 69) is connected to the first hand lever (41, 43, 49) by a second stationary hinge, which is offset in parallel to the first hinge, an elongated coupler has third and fourth hinges (8, 9) on its ends, the third hinge of which being hinged at the free end of the drive lever at an axial distance from the first hinge and forming a first hinge pair (2, 8) with it, and the fourth hinge being hinged at an axial distance from the second hinge to the second hand lever (61, 63, 69) and forming a second hinge pair (3, 9) with it, the two hand levers (41, 43, 49; 61, 63, 69) and the two cutting elements (42, 52) form a four-hinge system formed by hinge bolts of the hinge pairs (2, 8; 3, 9), wherein the distance of the hinges of at least one of the hinge pairs (2, 8; 3, 9) is changeable in that the fourth hinge arranged on the second hand lever (61, 63, 69) is axially displaceable in a slotted link in the form of a slot guide within this lever between a first position for a normal cut and a second position for a power cut at an increased reduction ratio, and is resettable into the position corresponding to the normal cut by a first spring element, characterized in that a power cut latching device is provided, which after the hand levers (41, 43, 49; 61, 63, 69) have been moved apart completely, holds the displaceable hinge in a position corresponding to the power cut, and is releasable by merely moving the hand levers (41, 43, 49; 61, 63, 69) completely towards one another, so as to enable a return movement of the displaceable hinge by the first spring element into the position corresponding to the normal cut.
