A shepherd's crook is not only an image that appears in ancient to modern art, but is also a very useful tool for shepherds who are navigating fields of varying height or uneven terrain. The crook symbol, a stick with a c-curve at the top, looking much like an oversized candy cane, has been in existence for millennia. The crook and the flail were two symbols associated with the ancient Egyptian god, Osiris. Pharaohs carried such crooks to evoke the godlike nature of their rule, and also as symbolic that they shepherded or led their people. You will also see numerous depictions in art of Jesus Christ carrying a shepherd's crook, since he is frequently referred to as the shepherd of Christian followers.

Early versions of the shepherd's crook were likely carved or constructed from wood, or often horn. In fact the crooked handle may be called the horn. Length of the staff is variable. A shorter person would want a shorter crook, with the handle no higher than, or slightly below the hip. As with any walking cane, a shepherd, a goatherd, or a herder of any animals might find the crook extremely useful in walking across difficult or changing terrain. When not in use, the crook could be hung over the arm.

In modern times, you’ll still find many shepherds and goatherds, especially in the British Isles, who use a shepherd's crook on a daily basis. While some still prefer the feel of carved wood or horn, others prefer a more modern version of the crook. You can certainly purchase elaborately carved crooks, many as useful as they are ornamental. A newer trend is to offer shepherd’s crooks in light but sturdy metals. There are fans of both old and new forms.

Prices for the elaborately carved wooden sticks, which may be all or at least partially handmade can be particularly expensive. You can expect to spend at least 300-400 US Dollars (USD) if not considerably more for the more elaborate crooks. Aluminum crooks are lighter in weight, and some may be more durable than their wooden counterparts. These may cost about 20-40 USD depending upon where you purchase them. You can also buy fairly simple mass-manufactured wood crooks for approximately the same price.

Not only does the shepherd's crook serve as a walking stick, with many people using them only in that manner, but they may also serve a significant function in the shepherding world. The curved handle is normally wide enough to fit around the neck of a sheep or goat, allowing a herder to catch an animal that is straying and reroute them to a different direction. A crook might also have been used to hold a sheep in place while the animal was shorn. This is not common today; most sheep are tethered during the sheering process.
