It is very near identacle to the Triska and Sonoran. All three have blades enclosed inside the furrel.
Big BULL
The HyperShock BLADES ARE NOT "NOT" ENCLOSED IN THE FURREL. That is what the major problem was with the heads of the past. The HyperShock blades pass though the body with the sharp side sticking out of the farrell and when compressed the tips of the blades expand out fast, and that is just one difference this is not at all like any broadhead you have seen. You must know all the facts before comparing broadheads to broadheads. Go to there web site and read all the differences the HyperShock will blow you away!
