You're using really low grits. On mine, if my blade REALLY needs a sharpening, rather than a straightning, I start out with 150w/d or 220w/d. If it just needs touched up, I usually start around 600, 400 if it really needs it. I polish it up on 1500 and then go up to 4000, then strop with 6000grit paste and green compound, which is almost the same. Lower grits, buy in emory paper kind, higher grits, get the wet/dry kind. It should help. Full sharpening cycle for me goes(if I am establishing the bevel) 150 emory paper, 220 emory paper, 400 w/d, 600 w/d, 1500 w/d, then 4000 w/d. Strop on green compound and done. Straightening the edge back up, I would drop back down to 600 w/d and go back up from there.
