Fifi hook

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 and mixed climbing.

Typically made of stamped steel or forged alloy, it has a large hole at the bottom for connecting to one's harness and a smaller hole at the top for attaching a retrieval cord in case of a fall.
