Breakdown The Hypodermic Trypan Broadheads are some of the best broadheads Rage has ever produced. With a streamlined titanium ferrule and a 2" cutting diameter, the Trypan creates an entry wound in excess of 2.5 inches. Afterward, the Trypan’s .039" thick stainless steel blades settle into a sweptback blade-angle configuration. In-flight, the overall diameter is only 3/4" making the Trypan a very accurate and stable broadhead. The grey polymer Trypan-specific Shock Collar provides exceptional blade retention and consistently reliable blade deployment. The one time use Shock Collars are keyed to notches in the Trypan’s titanium ferrule, so they never can be put on incorrectly. The Trypan is an excellent option if you are looking for a sturdy, razor-sharp, field tip accurate mechanical broadhead.
