Was in a antique store and picked up this old Rastus. It has some pitting, it's straight no smiling, no hone wear on top edge. Thoughts on polishing it up? 0000 steal wool? 240 320 460 600 1000, 1500 sand paper, Grey paste, white, then red. I polished up a keenkutter with some success but i want to do the best I can to remove as much of the pitting as I can. What are any thoughts or suggestions?
