The Swhaker 100 Grain 2 Inch Cut 3 Pack Mechanical Broadheads have blades that stick out just 1 inch during flight and then expand to 2 inch blades upon impact with an object. The blades are constructed of hardened high-carbon steel and are razor sharp with a diameter of 0.032 inches. An anodized aircraft aluminum construction gives these broadheads the toughness needed to punch through the tough hide and bones of the biggest game in North America. Each package comes with 3 broadheads.
