Polishing is the same as honing or sanding wood "D" you start at a lower grit and when all those scratches are even then you move to the next higher one... If you used a flap wheel your scratches are running spine to edge, so you want to start at the same grit wet-r-dry and sand from heel to toe until all the scratches are even and lengthwise... Once that happens you move up in grit and continue... Some people switch directions every time they switch grits too.... Continue until one of three things happen...

1. You give up and send the ******* thing out here to me or out to Max

2. You get a really good cut, and send the ****** thing through a wall

3. You get to a point that the steel starts looking good to you, and you say "Huh, I restored a razor"
