I keep hearing people say, "unless the blades are really really sharp, there won't be much of a blood trail on pass through". Maybe it is just me but I don't get it. If the arrow passes through the animal, it has to have cut on the way through, correct? If a "dull" broadhead doesn't cut on the way through a pass through shot, then what is is doing, moving things out of the way saying, "ok please move out of the way lungs, please move out of the way heart....ok thank you now I will exit out of the skin...thanks"?

I am not advocating dull blades, but isn't a pass through, a pass through?
Thoughts?

This is what I have edited to my original post...below:

I think maybe I did not explain myself better in my first post....this is what I wrote, " "unless the blades are really really sharp, there won't be much of a blood trail on pass through"."

I was really just comparing very very sharp broadheads as compared to those "less" sharp. "less" sharp meaning those that are still sharp, just not deadly sharp like some of you like to have them. By saying "dull" I meant comparitvely to the extremely sharp heads. BELIEVE methat is what I meant
