I think I know what Cutiss is thinking..... :confused:
Years ago (in the "compound" days) The "Razorback 5" broadhead was all the rage.
The broadhead was designed with a blade "cartrige" that spun freely on the screw-in shaft. The logic being that an arrow spins through the air,but when the broadhead hits the target the arrow stops dead.(i.e.spinning) retarding penetration.With the "Razrback 5" broadhead when the broadhead stops,the arrow shaft continues spinning providing that extra "push" and increasing penetration.
It's a good concept.....I don't know weather it works or not.....but it seems better than todays "faster is better" compound mentality.
