This knife has everything IMHO. It is an automatic OTF (Out the Front) Knife with knuckle buster holes (Brass Knuckles) and a sharp on both sides dagger blade. It also has a glass breaker at the end for rescues or as I like to call it, a skull crusher. Very nice deployment and all around badass knife. Collectors, don't wait. I only have two in stock and when they're gone, they're gone!
