How do odd-shaped abrasives compare to round or dull abrasives during the polishing process?

Odd-shaped abrasives are designed with irregular forms, which allows them to engage with the surface being polished in a more aggressive and effective manner. This increased engagement leads to a higher rate of abrasion, meaning that they remove material from the surface more quickly compared to round or dull abrasives. Consequently, their unique shapes create more grooves on the surface being polished. This characteristic can be particularly important when trying to achieve a specific finish or prepare a surface for further restoration processes.

In contrast, round or dull abrasives tend to provide a smoother finish as they distribute the polishing action more evenly across the surface. While they may be effective for certain applications, they do not abrade the surface at the same speed or intensity as odd-shaped abrasives. Thus, when the goal is rapid material removal or a more pronounced texture, odd-shaped abrasives are a more suitable choice.
