This 5″ diameter, 38 ply, 8 rows stitched, Razor-Edge, Yellow Muslin Buff has been chemically treated which increases its thickness for better surface area coverage. Razor-edge buffs can reach into areas where conventional buffs cannot, such as corners, channels and slots. Excellent for cutting with tripoli when used on soft metals.  Can be used for cutting or for polishing when used on harder metals, like platinum, palladium, steel and stainless steel. Lasts up to three times longer than untreated white buffs. Made of fine-weave muslin with combed edges with a leather pinhole center. Highest quality thread count: 86/80.  Made in USA
