Another interesting snippet about it not mattering what the low grit hones do:

page 23:

"The edge quality was independent of the size of the burs left from the original grinding with either 600 grit or 1000 grit wheels. The coarser original burs of the as-ground 600 grit blades and the finer burs of the as-ground 1000 grit blades were both replaced with similar edge geometries."
