Rage Black Series Chisel 2in Fixed Blade Broadhead - 3 Pack - The Rage Black Series 2 Blade Chisel Tip is a combination of Rage's most popular shock collar models. The aircraft-grade aluminum ferrule is machined to scrupulous specifications, anodized black, and assembled with Rage's sharper-than-ever 420 SS blades. The hardened steel chisel tip features a proprietary design to help bust through bone and create micro-fractures to allow the main blades to successfully pass through while retaining as much edge as possible. The 2 cut rear deploy main blades stay locked in place in your quiver and inflight thanks to Rage's proven Shock Collar Blade Lock technology. The Black Series comes with 6 shock collars 3 Black Collars for use with vertical bows and 3 Red collars for use with crossbows. Each collar has 6 petals and can be used up to 3 times (once per petal). Once the .035 blades encounter hair and hide they push rearward and deploy into a massive 2+ cutting diameter, leaving a massive entry wound and providing unparalleled blood trails.
