I'm having some problems honing my 6 month old Dovo Special.

Background: The magic marker test showed that there was a 1 cm wide spot in the middle of the blade that was a 1/4 mm deep frown. So I honed it on a 800 grit waterstone until it was gone (approx 2000 stokes). Also, one of the inner stabilizers and the adjacent section of the spine were holding up the heel, so I dremeled the stabilizer a tiny bit to adjust the thick part of it's curvature, and honed the razor using a 45 degree stoke on the 800K stone until the offending spine area was flattened (this only took about 800 strokes). It now lays nice and flat on both sides.

Issue: One inch on the back side of the toe requires me to use a rolling X to get it sharp. I tried the 45 degree paintbrush stoke (my preference), a 45 degree X stoke, and a straight X stroke, but it didn't seem to make any difference. Even with lots of rolling X stokes, the bevel on that side of the toe is only about 1/4 mm tall, but is about 1 mm tall on the toe of the etched side of the blade. The magic marker test reveals that about 1/2 cm of the heel on the same side also doesn't get touched unless I use a rolling X stroke. I checked the edge against a straight edge. There is a very tiny smile with about 3/16 of a mm of rise at the toe and about 1/8 of a mm at the heel. Does that tiny amount of smile usually require a rolling X ?

If I breadknife the edge until flat, and reset the bevel, will I be able to use a 45 degree paintbrush stoke for honing from then on - or do these minor variations in spine straightness and grind thickness along the edge come back after a few sharpenings ?

Also, this is my first straight. Are most razors staight and flat enough that a 45 degree paintbrush stoke will yield even bevels, or do most have the small amount of warpage etc I'm finding on my Special ?

ps: I lap my stones every 15 minutes using wetdry paper on plate glass & lapping the pencil grid off twice each time, so I'm sure they are flat.

Thanks.
