JB,
Welcome to the forums. You can special order plain models with the hollow grind section satin finished. A few dealers carry them like this too.
Chris Reeve Knives does one of the nicest satin finishes around. If you are looking for a user though, I would recommend sticking with the stone washed finish. It hides scratches really well. The CRK website has all the details for Sebenza options (satin finish, blade swedge, double thum studs, etc.).
