Rage Hypo 2 100gr 2 Blade Broadhead - 4 Pack - Rage Customers asked and we delivered. The Hypo 2 is an improved Shock Collar version of our original Hypodermic Series of Slip Cam Broadheads, featuring a triangular keyed shock collar that only allows the Shock Collar to be installed in the correct orientation to eliminate improper installation. Once in place the tried and true Shock Collar blade locking system holds the 2 razor sharp, .035 stainless steel blades closed until impact. Upon impact, the blades instantly deploy to a 2+ inch cutting diameter, administering the gaping wounds that bowhunters have come to expect from the field-proven Rage Hypodermic series. The keyed Shock Collar also allows for all 6 pedals to be used; simply remove the collar, spin 120 degrees and reinstall. The Hypo 2 features an even sharper Hypodermic hybrid tip and more swept blade angle for increased penetration. In flight, that streamlined design makes for superior field-tip accuracy. The two .035" thick blades deploy on impact, sliding into a swept-back blade angle while the monstrous 2" cutting diameter delivers an extra wide "Slap Cut" entry hole for gruesome blood trails and brief tracking jobs.
