These stitched buffs have multiple concentric rows of stitching which stiffens the buff.  Generally, stitched buffs are used for cutting compounds (such as Tripoli) on soft metals.  On harder metals like platinum, palladium, steel and stainless steel, Stitched Buffs are used for both cutting compounds and polishing compounds such as rouge.  Made in USA.
