Yes, we agree. If you want an authority on how heads do slice through an animal, I would point you to Dr. Asby's studies. Most of his findings show two bladed, single side sharpened (like a razor blade) grizzly's go throughgame about the best. His studies are based on actual game. I also agree that I can getMuzzy bladessharper on my own then whatare out of the packet.

They are one tough reliable head though that will probably not fail mechanicallyif heavy bone is encountered (as shown by the cast iron test). It seems they are one of the standard headsto rate other heads by (just ask 5-shot). Can't go wrong with them.

Iwould disagree withyou though about the CORRELATION of blade sharpness and and having intestines plug up the hole.
First, because of the location in the anatomy ofdeer, I would see no logical reason to purposely put an arrow through the intestines evenon quartering shots. Intestines are located behind the stomach and are in the back half of the deer. Ifthe deer is quartered away too severely, you will not be able to take out both lungs (and hit intestines). Quartering to, head on,rear shots should not be taken.
Second, if a deer is hit through the intestines or stomach, it is very common to have the holes plugged. But this does not neccessarily happen exactly at the shot. It happens more from the deer moving/running/walking and working the matter through the hole. Or from the inerts moving inside the animal, not lining up the wounds of the stomach/intestine and the exit wound. This is a common reason of a great blood trail to start becoming sparse.
