Shepherd's crook
A shepherd's crook is a long and sturdy stick with a hook at one end, often with the point flared outwards, used by a shepherd to manage and sometimes catch sheep. In addition, the crook may aid in defending against attack by predators. When traversing rough terrain, a crook is an aid to balance. Shepherds may also use the long implement to part thick undergrowth when searching for lost sheep or potential predators.Symbolic use
