how did it do that to that doe. i dont understand.
Just incase your not joking, in theory kinda works the same way as if you poke your finger into a bed mattress.
The outside diameter of the area you touch moves towards the center where you poked.
So if you had blades on the sides of your finger, you would cut further from the point of impact thus making a larger cut. This theory will be the same for all broad heads i think.
Just a theory of mine, wonder how many will agree to this in some way or another.
