The 125 Grain Gravedigger is a hybrid head in the true sense of the term. The and quota; cross opening and quota; blade design greatly reduces the energy needed to open the blades compared to traditional and quota; over the topandquot; mechanicals on the market. With its exclusive fixed-blade mode, the Gravedigger can be shot as a 1-inch fixed main blade with 1/2-inch bleeders simply by tightening the set screw on the kick out blades. The mechanical blades are sharpened to the point, allowing them to penetrate the hide and deploying inside without sacrificing kinetic energy that is lost with other mechanical broad heads. With its patented blade-retention system, the Gravedigger blades stay closed in flight, but open on entry - every time. This hybrid head is a no-fail option for every bow hunter, giving you the best of both worlds.
