Zusammenfassung:	A method of making an abrasive particle distribution includes: sorting an initial lot of abrasive particles into a plurality of sublots including first and second sublots of the abrasive particles according to their average particle diameter and aspect ratio, and combining the first and second sublots. The initial lot conforms to an abrasives industry specified nominal grade. The first sublot has an average particle diameter and aspect ratio less than the second sublot. A sum of the first sublot and the second sublot contains fewer abrasive particles than the initial lot. The resultant abrasive particle distribution and abrasive articles including the same are also disclosed.
