As with all WASP SST broadheads, the Jak-Hammer 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 on impact and fold back to a cutting diameter of 1-3/4 inches.
