i just don't think there is a single inexpensive hone that can fix your razor.
the DA seem to need more than just honing.

once the shoulder is fixed i think some people have used lapping film to hone those.

if you don't have a spectrum of hones capable of taking a razor from chipped to shave-ready, or not able to get somebody else do it for you your $15 razor may be just a waste of $15.
