I wonder if your rolling the blade edge or stone as you work the edge?
As a knife-maker, I have watched & tot many guys that just can't seem to get a good edge on a blade and the problem is usually one of these issues.
1. Not keeping a consistent edge angle while working the edge.
2. Pushing too hard (trying to remove too much material with each pass)
3. The steel in question is too soft or too hard
4. Not being patient enough during the process
5. Getting the edge pre-sharp (meaning you've actually got a bur edge which is good. You just need to use a ceramic rod or stropping leather to remove the bur) which if stropped will give you a razer edge!
I don't know what your problem is, I hope one of these normal problems is it and you can pick it out and fix it.
If not, and time is really running out, my suggestion is either take your heads to someone who can sharpen them for you or go get some new ones that are all ready sharp.
