A blade for an unducted fan of a turbomachine includes an airfoil formed of plural airfoil sections that are stacked along an airfoil axis. A difference in sweeps corresponding to a difference between a leading edge sweep and a trailing edge sweep is negative, and substantially between −30° and 0°, for any airfoil section whose height is between 10% and 30% of an airfoil height of the airfoil, and is positive, and substantially between 0° and +40°, for any airfoil section whose height is between 50% and 90% of the airfoil height.
