Greetings.
I too had this problem. When I got my first CF spydie, a fellow forumite had put a beautiful matted finish on it with 220-grit paper and a brush. It is beautiful.
I got a second, and was horribly disappointed by the fit and finish of the CF scales. The CF itself was flaked around the screw holes and lanyard hole, and frankly, the polished finish looked like cheap plastic.
Because I am NO finish carpenter, I sent a note to Spyderco, and asked what they would charge to refinish it for me. They said "we do no custom work" and "if you alter it the warranty is void".
Oh.
So, I have sent off to a fellow forumite who knows how to do all kinds of knifey things. You all know him. When he's done, we'll post pics.
