I'm not certain but it sounds to me like too much pressure and too coarse of hones and you are getting a sawtooth edge. I suggest trying this, lightly kill the edge on the edge of you hone or on your finger nail, then return to setting the bevel on your 1500 grit hone. If you get really deep stria from the DMT or the 800 it takes a long time to hone past those and they are what typically causes a very toothy new bevel.
