The fifi hook is a small question mark shaped piece of equipment used principally in aid climbing to quickly connect a climber to gear to take their weight. It can also be useful for free climbing, alpinism, mixed climbing and ice climbing.
Due to its open shape it offers very little strength and requires a great deal of caution when used. If a fifi hook is being used as a main rest support, using a backup carabiner is recommended.
