Sheepdog Crooks: Tools for Working Dogs and Livestock

What Is a Sheepdog Crook?

A shepherd’s crook (also called a cromach, cruca, or hyrdestav) began as a practical working implement on farms and hillsides. While once indispensable for managing livestock, over time crooks have evolved into prized items at country fairs, sheepdog trials, and traditional craft shows across the UK and beyond.

The crook is the hooked end, used by shepherds and stock handlers when working sheep. In day-to-day farming, a crook is a practical handling tool rather than a training aid, allowing sheep to be managed safely without unnecessary stress or physical contact.

What a Sheepdog Crook Is Used For

• Rescuing sheep that are cast, stuck, or trapped
• Hooking a sheep’s leg to regain control in confined spaces
• Blocking exits and controlling gateways
• Funnelling sheep through pens, races, and handling systems
• Extending reach when direct handling is unsafe or impractical

A crook is a control and safety tool. It is never used to strike sheep or dogs. Correct use reflects good stockmanship rather than force. For more on this approach, see our stockmanship guide.

Working Crooks vs Trial Crooks

Not all crooks are designed for the same purpose.

Working Crooks

A working crook is built for regular farm use and physical handling. Many are simple, practical tools — often nothing more than a solid wooden shaft, such as an old broom handle, fitted with a cast iron hook.

• Designed to withstand daily use and rough conditions
• Used for leg catching, lifting, and freeing sheep
• Commonly used in yards, pens, trailers, and gateways

Trial Crooks

Trial crooks are primarily used in sheepdog trials and demonstrations. They are lighter, more refined, and intended for visual guidance rather than physical handling.

• Not designed for leg catching or heavy work
• Rarely used in active farm handling
• Chosen for balance and ease of carrying during trials

Using a trial crook for working sheep is generally impractical, as they are not built to cope with the level of wear involved in farm work.

Choosing the Right Crook

The right crook depends entirely on how it will be used.

• Weight and durability for working conditions
• Length suited to the handler’s height and reach
• Whether the crook is intended for farm work or trials

A working crook should feel solid and reliable, while a trial crook should be comfortable to carry and easy to handle for extended periods, whilst they’re also bought for the looks as they can be decorated, especially on the horn.

Types of Horns Used on Sheepdog Crooks

The shape and style of the horn on a sheepdog crook determines how it is used. Different horn designs have developed for specific handling tasks, particularly in farm work where reliability and control matter more than appearance. This image shows a traditional working crook made of iron.

Open Hook Horn

The open hook is the most common and practical horn used on working crooks. It allows the handler to quickly catch a sheep by the leg when necessary and release it without excessive force. The gap in the hook needs to be that of an old penny in shepherd terms.

• Best suited for catching a sheep’s back leg
• Easy to apply and release under pressure
• Commonly found on traditional farm crooks

Closed or Shepherd’s Curl Horn

A closed or tightly curled horn is more commonly seen on traditional or trial crooks. While visually distinctive, it is less practical for active farm work.

• Limited space for securely hooking a leg
• More decorative than functional
• Primarily used in trials or ceremonial settings

Wide Throat Horn

Some working crooks feature a wider throat near the base of the horn. This allows greater control when blocking movement or guiding sheep through narrow spaces such as races or gateways.

• Useful for blocking and directing movement
• Less focused on leg catching
• Favoured in handling systems and yards

Traditional Materials: Horn, Wood & iRON

The classic shepherd’s crook combines two natural materials that have been used for centuries:

• Rams Horn: Traditionally used for the crook head (the curved top), rams horn is preferred because of its size and strength. Horn from ewes is generally too small and thin for carving and everyday use. Ram horns consist of a solid bony core surrounded by a permanent outer sheath of keratin – the same durable material found in human hair and fingernails. This natural structure provides strength while allowing the horn to be shaped once prepared.
• Hazel Wood: The straight shank or stick is usually crafted from hazel, prized for its light weight, tensile strength, and natural bark colours sought in competitions.

On working crooks, horns are typically made from cast or forged iron due to their strength and durability.

These materials make a crook that’s both functional for shepherds and beautiful in finish.

How Shepherd’s Crooks Are Made — Step-by-Step

Creating a handcrafted shepherd’s crook is both an art and a craft. Each horn and stick is unique — so experienced makers adapt as they work.

1. Preparing the Horn

The process begins with selecting a large rams horn. This is boiled to soften it, then compressed in a steel press to remove the original curl and blend the interior core with the outer horn.

2. Heat & Compression

Repeated heating and compression refine the horn’s shape. The aim is to produce a rounded, workable section that can form a smooth, circular crook head.

3. Forming the Curve

Using heat and wooden formers, makers bend the horn into the classic hook shape. After cooling, careful rasping and filing refine the profile.

4. Joining Horn to Wood

A snug fitting hole is drilled into the horn’s neck and matched with a carved peg on the hazel shank. Once glued and secured, the crook begins to take its final form.

5. Finishing & Decoration

Depending on style, crooks can be left plain or decorated with carvings – often depicting Border Collies, thistles, or pastoral scenes. This decorative carving is a tradition at many UK fairs

Using a Crook Alongside Sheepdogs

When working sheep with dogs, a crook supports the handler rather than replacing the dog’s job. It is used to manage gates, control space, and deal with individual sheep while the dog maintains pressure and movement.

• Holding gates while the dog moves sheep through
• Blocking breaks and stopping sheep turning back
• Assisting when a sheep needs to be caught or lifted

The crook complements voice commands and whistles, allowing the handler to stay positioned correctly while maintaining control of the flock. See our guide on using sheepdog whistles for more on handler communication.

Summary: Shepherd’s Crook – Form, Function & Folklore

From a practical tool for moving livestock to an artisanal heirloom, the shepherd’s crook embodies centuries of shepherding heritage. Its creation requires skill, patience, and deep respect for natural materials like horn and hazel wood — qualities that mirror the bond between shepherd and sheepdog that defines hill farming culture across the UK.
