If you want the power of both a fixed blade and mechanical broadhead, load up with Trocar HB 4-Blade Mechanical Broadheads from Muzzy. The innovative design features a steel ferrule with a chisel tip for impressive power upon impact. The Trocar HB has the ability to produce a 1" fixed blade cutting diameter for focused, accurate impact without sacrificing on speed, or a 1-5/8" expandable cutting diameter for greater penetration. This blade combination allows you to customize each shot based on how you see fit, resulting in greater hunting and shooting success. Two offset fixed blades induce spin and increased speeds. The Trocar HB 4-Blade Mechanical Broadheads come in a pack with three 100-grain broadheads.
