Innovative blade-retention system is not only strong, but allows the blades to pivot independently of each other when contacting bone. Rear-deploying blades ensure massive entrance holes. Its low profile delivers field-point accuracy. Stainless steel tip offers bone-crushing performance up front and 1-1/2" cutting diameter provides excessive blood trails. Reliable blade-retention system prevents accidental blade deployment in your quiver or during flight. It can also be locked into practice mode and shot into standard targets without damaging the blades. 100 gr. only. Per 3.
