Our double bevel VPA 2 Blade broadheads really live up to their "Penetrator" nickname. They are CNC-Machined in one-piece from High Carbon Steel and heat-treated to 50-52 Rockwell. Their uniquely designed ferrule is faceted to match sharpening angle aiding in making them quite the little bone splitters. The ferrule supports the head all the way to the double tanto style tip to prevent tip curling.
