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.Designers and engineers from both companies collaborated over the course of two years to combine their knowledge of blade technology and materials for the ultimate in strength, surgical sharpness and precision to launch the WASP HAVALON HV fixed blade broadhead. Leading the way is the trademark Stainless Smart Tip (SST), a 100% stainless steel TROCAR tip that is designed for deep penetration through bone, hide and anything that comes in its way.
