Short term try honing heal first so the stabilizer and bottom 1/4-1/8" inch of the spines heel is not
resting on the hone. Ten heal first then ten sweeping X almost as if the only part of the
hone you are using is the near half inch (feeling not reality). Pressure can make
it worse as it flexes the blade in ways that are wrong for finer finishing grits.
I have some old razors that show a lot of wear toward the toe. Looking at them I see a sloppy ramp
honed on the stabilizer and odd wear at the spine transition to the shank/handle. The original
owner and now me -- avoid these bits and hone heal forward.
The picture looks like a darn fine nearly new razor except for the BK bit.
It will hone.
It may be the classic case of a factory edge not being an
edge that a home shaver can refresh with ease. If so is a good
example of why so many folk ride the "hand honed, shave ready"
train. Still, It will hone.
