At first I thought I had overhoned this W&B wedge, and maybe that's still the case. But I'm starting to think that there is something wrong with the steel. I've honed around 10 razors so far and have never had this type of problem. On the heel of the blade, I can chip off the edge with pressure of my fingernail.

The blade was pretty rusty when I got it and I needed to take out a couple chips. So I got out a low grit water stone that I use for household tools, taped up the spine, and went to work. I did use pressure and I wonder if I damaged the edge because after I honed out the big chips a bunch of new little chips showed up.

I tried to correct the problem by using light pressure for about an hour's worth of honing, but the edge just keeps crumbling away.
