1. An abrasive article comprising:

  • a shaped abrasive particle comprising a body having a first height (h1) at a first end of the body defining a corner between an upper surface, a first side surface, and a second side surface, and a second height (h2) at a second end of the body opposite the first end defining an edge between the upper surface and a third side surface, wherein the body comprises a normalized height difference defined by the equation [(h1−

    h2)/(h1/h2)] of at least about 40 microns, wherein h1 is greater than h2;

    wherein at least a portion of the upper surface has a curvilinear contour; and

    wherein the body comprises a bottom surface opposite the upper surface and having a substantially planar contour, wherein the bottom surface has a greater surface area relative to the upper surface.
