It's more for utilitarian purposes hahaha, I have a much more effective machete and bat in the closet, the machete was a gift from one of dads deployments pretty nice kbar style grip, pretty hefty blade and super sharp, hence it stays put up, don't want in dewey cox style halfings going on.
Although the knife in a last ditch hand to hand could allow for penetration of the cortex if you stab the rear underside of the head but I wouldn't wanna get that close haha. This video I'm posting is complete BS but it's kinda cool the way they shot it. Be interesting to know hwat movie or whatever this was filmed for.
