Do you consider unscrewing three screws and screwing in a different clip to be modding you knife? Because there are many other clips from other Spyderco knives that would fit on the Para 2 and that can be purchased for under $10 at the Spyderco Factory Store and used instead of the stock clip. Mine came with a shiny stainless clip and I wanted something more subdued so I ordered a black clip but there are other clips that would fit that are not painted.
It would also be pretty easy to just put a satin finish on black or shiny clip by sanding, or soaking it in paint remover. With the black paint removed chemically, the clip's remaining finish would probably be pretty dull looking.
