The Rage Black Series 2 Blade Chisel Tip is a combination of our most popular shock collar models. The aircraft-grade aluminum ferrule is machined to scrupulous specifications, anodized black, and assembled with our 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 our 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.
