I have a DOVO Bismarck that I've had trouble getting sharp, so I did a little investigation, and thought you all might be interested in what I found.
I had somehow accidentally put a secondary bevel on the edge. The only way that I could think of was that sometimes when I'm honing the razor, I accidentally let the handle end drop a little as I'm drawing it across the hone. This causes the tip to raise off the hone, and ends up putting some extreme pressure on the edge, as it is hitting the edge of the hone rather than spreading the force out over the face of the stone. That's my guess, anyway. I had to use my Radioshack 60x hand microscope to see this. If you don't have one of these, they were about $15 at Radio Shack a few years ago. Great device!
To repair the damage, I decided to try using a Spyderco fine ceramic stone, then switching to the ultra fine for final honing. I used the Sharpie method. Note - always mark with a sharpie as if stropping. Even a dull razor will take the tip right off. Anyway, I found that if I use my free hand index finger behind the razor (touching the stone), it steadies the whole process enough that I don't lift the tip. I'm not pushing down, just holding my finger on the stone and on the spine of the razor at the same time. Much steadier (for me) than one handed.
It took a grand total of 5 strokes per side on the fine ceramic to completely reprofile the razor. I was surprised, this is some pretty thin metal. Then I gave it 10 strokes per side on the ultra fine, and it is now shaving properly. I have some very fine Lee Valley sheets, don't remember the grit size, but I'm thinking 0.25 micron. Did 10 strokes per side, and now it shaves sublimely. And I haven't even stropped it yet.
Anyway, if you find that honing isn't doing the job for you, you might want to look closely at your edge and adjust your technique. This has made all the difference for me.
Does anyone know of a good mirror that you can hang on a wall, like the old "vanity" mirrors? Part of the problem that I have is trying to see what I'm doing while leaning over a sink. After a while, it's hard to be steady when my old back starts talking to me...
