I do a lot of blade sharpening, bH's and knives, have did several for forum members. I have read, and have had several Doctors that are friends tell me, that a seratted or rough edge, tears up the edges of veins, arteries when passing throug, displaces the tissue of them, that they cant seal off as easy as those cut with a razor sharp. This is in muscle tissue and internal organs. I have shot animals with heads sharpened both ways, got about the same result, but did seem to get better bloodtrails with rough edges that were" good enough". This is the theory behind the Magnus Stinger Buzzcut and the older Kolpin Terminator serrated edge broadheads that came out in the 1980's. My brother in law killed a bunch of deer with those and a wheelie bow.
