Hi Everyone,
I have a question about broadhead blade angle as related to wound channel and blood trails. It seems that there are a lot of short broadheads with steep blade angles and short cutting surfaces being manufactured, which I'll refer to as "chisel" style heads because, if one was to open up the blade angle enough, the cutting surfaces would be flat like a wood working chisel and perpendicular to the arrow shaft. At the other end of this blade angle spectrum are long broadheads, with fairly narrow blade angles, and a lot of cutting surfaces. These I'll call needle style heads because if you were to make the blade angle shallow enough your blades would be parallel to the shaft and frontal cutting surfaces would be pin points. OK both of those names are exaggerations, but serve as conceptual models for discussion.
So my question is: Assuming the cutting diameter, blade number and orientation, and point of impact on an animal are the same, will chisel and needle style heads cut the same size wound channel, and hence allow for similar blood trails?
This question comes from discussion I've had with hunting friends. We've agreed that blade angle probably effects penetration (via amount of energy or momentum required- chisels needing more because of the steep angle). However, we have not reached agreement on the wound channel diameter.
What do you think and why?
Thanks in advance,
Stuart
