We have never sharpened a cutting wheel. When they get dull, which isn’t very ofter we just replace the cutting blade. We get ours from American Metalcraft part # PPC4 with the replacement blade # PCW4. The cutters are $8.00 and the replacement blades are $4.60. Rocker knkves are another story as they must be sharpened from time to time, but just a couple passes with a hand held,draw type knife sharpener keeps them cutting great. The same holds true for the “Equalizer” form Lloyd Pans, infact, they give you a sharpener with each Equalizer they sell. Something to ponder; Why are your pizza wheels getting dullede so quickly? Consider what you are cutting your pizzas on. If you are cutting on a metal table top, this might explain it, if so, consider purchasing a cutting mat or cutting board, these are a lot kinder to your cutters than bare steel.
