As with all Wasp SST broadheads, the Wasp Jak-Hammer 125-Grain Broadhead Arrow features a pre-aligned, Stainless Smart Tip (SST). The edges of the trocar, Smart Tip are factory-aligned with the rise of the three stainless steel blades creating a straight cutting path that opens a gaping wound channel, ensuring maximum penetration. The three surgically sharp stainless-steel blades of this mechanical broadhead fold forward in flight and are retained by an O-ring. Blades deploy upon contact and fold back to a cutting diameter of 1-3/4 inches. The pack contains 3 broadhead arrows.
