So if there was a milky slurry on the stone you should be using just enough pressure to have the edge slide under the slurry, so if you ease up just a touch on the pressure it should leave some behind. I also agree that if this isn't a razor that is somewhat expendable, perhaps you should rethink the strategy. here are quite a few shave ready razors for not a lot of cash in the classifieds regularly. My logic is that you really should learn to hone on a razor that is free of geometry issues and can take and hold a very nice shaving edge. There are quite a few for $50-75 that are in the classifieds often and periodically even cheaper than that. I think that would be your best avenue. Also if you could sit down with someone that would be the best. A 30X loupe is handy for checking to see if your scratch patterns are even too. It goes really well with the magic marker.
