I use both the buzz's and the plains and I sharpen both on a simmons clamp sharpener which is done exactly the same as the plain blade,, the serrateds do feel sharper to thr touch though..
I also agree with the wound channel theory advice some have mentioned,,,I think every single broadhead from every brand needs to be touched up to get to the proper sharpness and I don't care how sharp they think it is.. Also I do believe there is alot more blood that will bleed out alot longer with a fine cut from a smooth razor sharp blade,,,, even non lethal flesh wounds bleed forever it seems..
