Unless your arrow splinters, which I have never had happen on game, you wont have to worry about that. If you did need to trim up around a splintered arrow, you would lose a few mouthfuls at most. Even at the range I have never seen a spiral/multi-directional wound carbon arrow splinter more than an inch or so at most when impacting concrete or rock The first all carbon arrows to hit the market (unidirectional) had splintering issues and were a danger not only to the area around the wound but the shooter as well as damaged arrows could shatter in the bow at the shot, driving 30" long splinters into the shooters arm, this problem was eliminated 2 decades ago. I sure wouldn't chose my arrow based on the meat wastage argument.
