A very successful bowhunter once told me, he prefers less than razor sharp broadheads. not dull, but not brand new, believing a surgical cut from a sharp broadhead can cause less bleeding or the wound to seal up better since its a perfect slice, rather have a jagged cut/ or one forced through than cutting through. Something to consider, Now i dont worry about having a brand new broadhead thats razor sharp, usually keep a few for ongoing practice, then switch over to soem new ones and take a few shots, then use, so theyre not brand new after hitting the target a few times, but not worn either.
