I do a variation on the Musatto/Hill serrated for most broad heads, wide round heads like Deadheads get a combination treatment. Some heads have metal that holds an edge better if it is file sharpened and a bit rough, like Bears. My wife shot two Bears through a small buck two years back. One was re-sharpened in the field with just a file,(test shot an arrow into a bale) and the other was honed and buffed to an easy hair shaving sharpness at home. After passing through the deer the razor sharp head was dull, the file sharpened edge was still sharp. Not a scientific test, but an accurate observation. I suspect metal hardness makes that difference.
