I hardly ever go over 240 grit on the grinder....for blades, I find that I can hand sand from 240 to 600 more evenly and cleanly than I could ever grind with a 400 grit belt. I sometimes even do 80 grit, then draw file, then hand sand. I dont think it slows me down at all. If I convex ground, however, id prolly be taking everything way up in grits on the grinder. I usually have problems with grind lines wandering with a tiny bit of misplaced pressure on the finer grits, which for me un-does the benefits gained by avoiding hand sanding to those same grits.
