I gotta apologize I just told ya what might have gone wrong I didn't attempt to help you on the fix....

I would start at 320 grit sandpaper wrapped around the back of the spine and pinching the blade between my fingers and re-finish the blade.... As you pinch and sand, you should wipe off the old bevel and clean up the spine.... progress through 2000 grit, and you should end up with a nice level playing field to start your honing on....
