A coated abrasive article comprising:
- a substrate;
- and
- a plurality of abrasive particles overlying the substrate, wherein at least 5% of the plurality of abrasive particles are tooth-shaped abrasive particles,
- wherein each of the tooth-shaped abrasive particles comprises a body having a length, a width, and a thickness, wherein length>width≥thickness, and wherein the tooth-shaped abrasive particles comprises a body including a tip region including a tip of the body and a base region including a base of the body, wherein the tip region is defined by a taper including a reduction in the thickness of the body over a tip region length;
- and wherein a greater content of the tooth-shaped abrasive particles have their tip regions oriented closer to the substrate compared to a content of the tooth-shaped abrasive particles having their base regions oriented closer to the substrate.
