Loose – A Loose unstitched buff will be a very soft and flexible one. When used with polishing compounds, like a jeweler’s rouge, they are perfect for final finishing work. Since these buffs are loose, also described as unstitched, they are highly able to conform to whatever type of piece you are polishing as pressure is applied, making them perfect for things with contoured edges and curves. They also create a lot less heat than a stitched buff.
Sewn / Stitched – The stitched style buffs are the buffing wheels you will want to use with polishing compounds to produce a final, high polish to your workpieces. The stitching adds stiffness to the buff allowing you to apply more pressure against it. Depending on the buff you choose, the number of rows of stitching will vary: keep in mind that the more rows of stitching that it has the stiffer the buff will be.
