Hunters never leave home without a hunting knife, if only as a means to dress the animal after the kill. However, just like the hunter's knife, a Predator never disembarks his ship without a nifty set of wrist blades — and these puppies are definitely meant for up-close and personal encounters. Since the original 1987 film, every Predator has done battle with a set of wrist blades. Some Predators have even taken their wrist blades to the next level, like the Predators seen in the first "Alien vs. Predator" film. These alien hunters practically have swords attached to their wrists. In fact, it's a wonder that they can even maneuver with wrist blades as big as the ones seen in "AvP."
As far iconic weaponry is concerned, wrist blades are a true staple of the Predator's arsenal. They don't just maim and kill, they also help work just as effectively in skinning the kill and claiming a souvenir for the good ol' trophy wall back in the cozy cabin of the Predator ship. In short, never get close to a Predator. Actually, you don't want to be at a distance from them, either, for other reasons that we'll get into. Basically, if you see a Predator you're probably dead meat.
