The first fully fixed-blade broadhead from Ramcat, the Diamondback Broadhead features an offset-blade design that delivers true field-point accuracy. Its concave design and the patented Airfoil System found on the ferule combine to reduce wind planing. They also reduce friction down the arrow shaft, resulting in deep penetration. One-piece stainless steel body. Blades sharpened front and back. Firenock Aero Concentric technology and Back-Cut technology. Per 3.
