If you want it satin, you need to sand that rough area. Start with 80 to 120 grit. Use light pressure and avoid overheating the steel. Keep the blade moving and try to maintain the same amount of pressure through a smooth even stroke. Take your time. When the rough areas are no longer visible, go to 180 to 220 and it will look almost like a factory satin finish. Scotchbrite takes forever to remove that rough steel. It will do well to shine up the smooth ground part of the blade, though.

ps It's looking good so far. You can do this. <img src="/ubbthreads/images/graemlins/thumbup.gif" alt="" />
