1. A blade for a mowing unit for a lawnmower and/or a motor scythe, comprising:
a substantially parallelogram-shaped blade;
wherein the blade has a slot,
wherein the slot is designed to receive a blade-holding element of the mowing unit such that the blade is rotatable about the blade-holding element and movable in translation relative to the blade-holding element for one cutting position of the blade defined by one end of the slot having one cutting orientation of the blade and another cutting position of the blade defined by another end of the slot having another cutting orientation of the blade,
wherein a line segment delimited by the one and another ends of the slot does run non-parallel to sides of the parallelogram,
wherein the parallelogram has an obtuse internal angle, and
wherein at least one of:
the ends of the slot are each closer to a respective corner of a minor diagonal of the parallelogram than to corners of a major diagonal of the parallelogram, or
a minor-diagonal angle between the line segment and the minor diagonal of the parallelogram is smaller than a major-diagonal angle between the line segment and the major diagonal of the parallelogram.
