The Wasp Havalon HV features an aerodynamic, ultra-compact, aerospace-grade aluminum ferrule that provides field-point accuracy and easy tuning. The .035-inch thick surgical sharp stainless steel blades combine for a 1-3/16” cutting diameter. As with all Wasp fixed blade broadheads, the blades are easily replaced and each pack comes with three complete broadheads and 6 replacement blades.
