All this "razor sharpness" is another arguement I can't understand when we're flinging arrows 300fps.I like the doctors scapel comparrisons. Like a broadhead traveling at300fps needs to be as sharp as sombody cutting out a tumor in your brain. Makes for good posts and conversation I guess.
A dull blade pushes blood vessels out of the way rather than cutting them. Arteries and especially veins are very stretchy and resilient to cutting. Your 300 fps arrow isn't doing 300 fps anymore after impact and may hardly be traveling at all before it contacts tissues on the far side of the chest cavity. I don't think anyone will argue that a sharp head cuts better than a dull one and since the sharpness of our broadheads is something we can easily control, it's just prudent to do so.
