The Rage Black Series 2 Blade Cut on Contact is a combination of the most popular shock collar models. The aircraft grade aluminum ferrule is machined to extreme specifications, anodized black, and assembled with the sharper than ever 420 SS blades. The .040" cut on contact tip features an oval shape to improve durability, increase cutting surface and increase blood loss. The 2" cut rear deploy main blades stay locked in place in your quiver and inflight thanks to the 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.
