Our VPA Turkey Spur broadheads are designed for maximum energy transfer and quick kills on tough birds. The rear positioned Spur blades are sharpened at the outer most edge, giving a 1 1/8 cutting diameter. The forward facing edges are left unsharpened. The unsharpened facing edges, along with the space between forward and rear blades, aid in the rapid deceleration necessary for maximum energy transfer. VPA Turkey Spurs are precision-machined from one piece of High Carbon Tool Steel. This, along with our special heat treating process, provides the perfect balance of edge retention and strength. Heat treated to 50-52 Rockwell with a Black Oxide coating that increases durability and provides corrosion resistance. Our design makes a quick and easy job of sharpening and re-sharpening with just a few strokes on a sharpening stone or diamond hone.
