Hate to tell you but if you could not hone out such a small chip by regular means there is every chance that area is still not as sharp as the rest of the razor.

Something to consider. You hone & hone & hone on a 1k & the chip is still there. Obviously there is no stone contact at that point. Now you breadknife the chip away. You have not changed the grind or spine geometry. How has that changed the original problem ?
