If you insist on doing the corrective work yourself then be aware that the 1/4 hones are not good for this. They are to short.
Use instead a sheet of wet/dry sandpaper, 500 grit (use it wet), and lay it on a flat piece of tile/glass/etc.
The other major note is to not use a 90 degree angle when bread knifeing/shaping but use instead a 30-45 degree angle.
You will have much less work to do on the next grit.
Hope this helps, :)
