The Rage Hypodermic Trypan Crossbow features a needle-like, streamlined steel ferrule and 2-inch cutting diameter that creates an oversized slap-cut entry hole. The Trypan Crossbow's .039-inch-thick razor sharp stainless steel blades slide into a sweptback blade-angle configuration, and deploy to a monstrous 2-inch cutting diameter, the broadhead has a 3/4-inch diameter profile in-flight. The Trypan specific Shock Collars provide exceptional blade retention and consistent, reliable blade deployment.
