Cant believe I am gonna respond here. Is it possible to shoot a dull head through a deer? Sure it is but this is not a matter of physics it is a matter of physioligy. Trauma induces the release of platelets to a specific area which helps in the clotting process. All bodies do this to protect themselves. The less trauma induced the less of a reaction from the body to protect itself. (sharper= less trauma)

Would doctors rather see a clean cut or a jagged cut? Of course the clean one because they are trying to fix it. A chain saw wound is miserable for doctors to fix, but its tough to sneak up on a deer with a running chain saw too.

As far as the stone heads are concerned burnie is correct they can be knapped to 1 micron in thickness a surgeons scalpel on average is 25 microns in thickness.

just my 0.02
