Excellent discussion! I too, AGREE with the principles and responsibilities of using sharp broadheads. However bear with me as I play devils advocate here.

Define sharp.

I don't think it is any secret that what one may deem as acceptable another might totally refuse. For example compare a Montec G5 to a Steel Force or a Rocky Mountain. By comparison they are not in the same universe when it comes to sharpness. Even when "touched up" after being in my quiver a while I can't shave hair with the G5. However after taking a number of animals with all three of these heads, to be totally honest I see no difference in the blood trails.

Even a "dull" broadhead is not going to "push" or "slide" the lungs out of the way on a center punched animal. One of the dullest heads I ever used was a BoneBuster. If your familiar with these heads than you know that they don't even have a point that is pointed [&:][]. I spent a long time trying to get it sharp but never could achieve that "razors edge". Although I don't think taking two animals with a head makes me an authority, I can tell you that I couldn't tell any difference in the blood trail in comparison to other "sharp" heads. Here is the real kicker. On both sides of this head are two "bleeder blades" I call them blades but they are more like wings. They are only 1/4 inch deep and you can't really sharpen them. Upon examination of the animals I could see in detail where these unsharpened wings had cut their way through the animal and its vitals. Penetration was also a non factor.

I think a guy is fooling himself if he believes sharpness is not effected by hitting ribs or other bones on the way in. I have recovered heads that punched through both sides of the animal but never penetrated the earth that are jagged and notched. It doesn't happen with every shot but it certainly does occur. I do think this particular part of the issue however has more to do with the construction of the head than it is with sharpness.

I know a guy that shoots traditional equipment that made his own arrows and broadheads out of rocks. He indeed killed a deer with them. While that wouldn't be my style it did open my eyes and caused me to think about the equipment I was using. Again let me say that I agree it is a good idea to use sharp broadheads, I just have a broader interpretation of what "sharp" is now.
