Swhacker is an archery broadhead manufacturer in Covington, Georgia.
Its listing describes a two stage blade design in which a set of outer wing blades cuts the hide and opens the broadhead, ahead of the main cutting edges. The stated purpose is to spend less energy on the entry wound so more is carried into the animal.
The description of how the design performs is the manufacturer’s own. Broadhead performance claims are not independently certified by anyone, so comparisons between brands rest on the manufacturers’ own testing.
