A Grigri (or Gri-gri, Gris-gris) is a hand-sized rock-climbing device designed to help secure rock-climbing or rope-acrobatic activities. Its main characteristic is self-camming under a shock load. Belayers using a Gri-Gri need full-attention on their climber and skillful operation to ensure safety. Grigri is a trademark of Petzl, but the success of this tool is so huge that it's likely to become a common name.
