Just throwing this out there. How about the double bevel? I had two wedges that I was honing not too long ago, and posted a couple threads in the honing forum about one in particular that was really taking me for a canoe ride. Anyway, I was using Basil's coti at the time, and went to the coticule.be website and followed the wedge honing instructions there.

After spending a bunch of time on the Norton's, and having a massive bevel to show for it, this method cleaned the bevel right up, and both wedges shave incredibly well.

My two cents. Not sure if this helps or if it's a wrench, but that one wedge was giving me a headache from all the banging against the wall I was doing.
