This is good information. I have been exploring the available grits and have found 60, 80, 120, 220, 320, and 600 grit in the 4in x 36in belts. Obviously the lower grits are cheaper, but I hope to avoid buying what I do not need.

My best guess (since all is in transit from just being ordered) is that 80-120 is good for “setting the angle” and that 220-320 for cleaning up the edge before honing. While I use 600 grit manually for sharpening my HP blades, 600 grit may not be as effective on a powered “belt” system?
