You can repair the damage on the hones. Start with spine raised ~30* from the stone, and work till the chip is gone, then do your normal process of honing.
In regards to Dremel and polishing blades, you can make yourself a magnetic jig that will hold carbon blades in place while you polish. The jig allows to polish with wheel spinning in direction away from the edge.
You can read about the jig here for example
