The Work Sharp Felt Polishing Wheel is used for polishing and de-burring. Apply the included green honing compound to the felt wheel and you're ready to polish. This is used much in the same way you'd use a buffing wheel. The Felt Polishing Wheel works with both the Work Sharp 2000 and Work Sharp 3000 systems.
The WS2000 and WS3000 are sold separately.
