I don't think there's much, if any, difference between a broadhead that's a shade on the dull side, versus another one as sharp as a scalpel at 300+ fps - the KE behind the arrow will slash rightthrough any soft tissue it touches. The only way to know for surewould be to stick your fingers under the deck of your lawnmower and see what happens- and I don't think either of us is willing to try it.

Agree to disagree, I guess.
