If you're looking to get a crisp, clean edge on your solid-surface countertop, there are a few different methods you can use. One popular method is using an abrasive wheel; this will take off any roughness and leave you with a nice, even edge. Another option is to use a router; this gives you more control over the depth of your cut and can give you a really clean finish. Whichever method you choose, make sure to take your time and go slowly to avoid damaging your countertop.
