Abrasive article having reversible interchangeable abrasive segments

Abstract

An abrasive article is disclosed and can include a core and a plurality of identical segments extending from the core. The segments can be arranged on the core to form first abrasive article indicia on a first side of the abrasive article and second abrasive article indicia on a second side of the abrasive article opposite the first side. The first abrasive article indicia can be identical to the second abrasive article indicia. Moreover, the first abrasive article indicia can be offset with respect to the second abrasive article indicia.
