What does a bull hook do?

A bullhook is a tool traditionally used in the training and handling of elephants, typically made of a long handle with a sharp hook on one end. It is used to guide, control, or discipline elephants, often by applying pressure or discomfort. However, its use has been widely criticized by animal welfare advocates, who argue that it can cause physical harm and psychological distress to the animals. As a result, many organizations have moved towards more humane training methods that do not involve such tools.
