The actual cutting surface is relatively small, but the Annihilator cuts on contact while the scoop design punches a hole in game, pushing and pulling tissue to create a large wound channel. (The cutting surface area on the 100- and 125-grain heads works out to .180 square inches, with a cutting diameter of .910 inches.) The fixed head is designed to gouge holes instead of cut slits. This scoop-style broadhead does introduce some drag, but this is reportedly a feature, not a bug. Brown and Brodie say that the wedge puts drag in the right places for optimal flight stabilization.
