The Kung Fu Grip was a mechanism used in G.I. Joe action figures starting from the Adventure Team series. The idea behind the Kung Fu Grip is that the soft rubber hands on the figures would allow them to hold their weapons better. For added fun, it enables the player to position their G.I. Joes in action poses such as climbing up a mountain with a rope or swing from a tree. Although the concept had nothing to do with martial arts, the technology was christened as such.
However, as wonderful as the concept was, the drawback was the rubber material used. After an extended amount of play, the rubber still proved to be somewhat fragile.
