My question is what do you think of the cut on contact, fixed or other flip open broadhead versus the Swhacker design. This isn't a Mechanical or Fixed Head argument. My question is really the claim of Swhacker on its design. They claim the blades do not deploy upon contact and only after entry do they open inside the animal. The fresh cutting blades are inside the animal and not dull because of cutting hair and skin. Is this design not better than any other broadhead? The logic seems sound but not necessarily so unless you have another opinion. By no means do I think it's the best broadhead on the market. I took my best Buck with a 85gr. Slick Trick. I will be testing several broadheads soon and thought this would be a good question for seasoned hunters.
