I've got this eBay razor that is confusing me. It's a 6/8 J. Allison that had a big chip in the edge when I got it. It's almost a wedge, maybe a 1/4 grind.

I worked it for a while on my 4K Norton to get rid of the chip, and I noticed an odd bevel pattern forming. (I taped the spine with electrical tape during this.)

On one side, the bevel seems pretty even. On the other, in the middle the bevel is pretty wide, maybe near 1/8", while near the toe and heel it's almost nonexistent.

The blade seems to have a smile, so back and forth honing on the Norton doesn't seem to get things evenly.

Would it be worth my while to try to remove the current bevel by using a 90-degree angle on some coarse sandpaper, then start from scratch with a flat edge with no bevel?

Any tips for doing this? Will I wreck the razor?

I know a smile isn't necessarily a bad thing, but it's beyond my honing abilities to work with one at this point.

Also, what could be causing this? Is it something I could correct, by, say, selectively wearing part of the spine or something?
