Piercing Penetration: The concept behind this Havalon HV and the reason behind Wasp Archery's partnership with Havalon Knives is to bring the absolute sharpest blades to the industry. Wasp Archery has always been know for extremely sharp blades, but in a sport where every millimetre of difference counts, Wasp wanted to up their game even more. The Havalon HV was the end result of a year of testing evaluation to bring the finest broadhead, made in America, to the bowhunting market.
