After sleeping on it, I think that I will follow your advice and start over starting with my 1k with tape. No better time than now to learn how to deal with this condition.Chip, pit or any damage removal is a about the same if doing all on bench stones. Grind it out by honing and the bigger the problem the coarser the stone to start will save you a lot of time. If it is going to mean some serious steel removal I will sometimes tape the spine while I do the heavy work and then when about done at that stage of remediation I remove the tape and proceed as normal. It just saves eating the spine up.
BTW, I paid close to nothing for the blade, so I have nothing to lose, and I can always search for another Imperial that is in better condition.
