There is no reason to change something that works perfectly. Ramcat Original is the most accurate, deepest penetrating fixed blade broadhead in the world. It incorporates proven aircraft technology, Ramcat is the first fixed broadhead that flies exactly like a field point when shot from any bow, at any speed. It has a patented Airfoil System which creates field point accuracy while Firenock Aero Concentric Technology eliminates thread slip and the Back-Cut Technology features both front and rear sharpened blades that do as much damage penetrating a target as it does coming out. Hits like a Ram, Cuts like a Cat!
