Jointed Copper Full Cheek Bit

A Full Cheek bit (also called a "Full Cheek Snaffle") is a fixed-cheek bit design with long, straight bars (cheekpieces) extending both above and below the mouthpiece ring on each side.

Design

• The mouthpiece sits on rings, similar to a standard snaffle, but rigid bars extend upward and downward from these rings, parallel to the horse's face.
• The upper bars typically have small "keepers" or loops through which the bridle's cheekpieces can be attached, holding the bars upright and flat against the face.
• The reins attach either to the main ring itself or sometimes through slots in the cheek bars, depending on the design.
• Unlike a loose-ring snaffle, the mouthpiece cannot slide side-to-side through the horse's mouth because the fixed cheeks prevent it.

Function

• Framed, stable feel: The sidepieces give the bit a "framed" quality in the mouth, helping the horse feel steady and secure in the contact.
• Lateral/turning support: The long cheek bars act as a visual and physical guide. When rein pressure is applied on one side (e.g., in a turn), the opposite cheek bar presses gently against the side of the horse's face, reinforcing the turning aid. This makes it especially useful for steering and bending, and helps keep the horse's shoulders in place through turns.
• Prevents pulling through the mouth: The bars stop the bit from sliding sideways or being pulled through the mouth, which can happen with loose-ring snaffles on horses that evade contact by turning their head sharply or leaning on one rein.
• Protects the mouth corners: The fixed sidepieces prevent the mouthpiece from pinching or rubbing at the corners of the mouth, a common irritation with bits that can slide or rotate more freely.
• Mouthpiece stability: Because the cheeks are fixed, the bit sits more quietly and predictably in the mouth compared to a loose-ring design.
• No poll leverage: Like the Baucher, the Full Cheek has no lower shank/curb chain combination, so it does not create true leverage or added poll pressure — it acts on the same direct, non-leverage principle as any snaffle.

What it's good for

• Green or young horses: The visual/physical cheek support helps teach steering and lateral cues, since the horse gets a clear tactile signal from the cheek bar pressing against its face during a turn. It's considered a great, comfortable starting bit for a youngster.
• Horses that struggle with straightness: The lateral guidance helps riders reinforce direction, useful for horses that tend to drift, bulge through a shoulder, or evade turning aids.
• Horses that root or lean, or try to pull the bit through their mouth: The fixed cheeks resist this kind of evasion better than a loose-ring.
• Horses with sensitive mouth corners: The stability and corner protection make it a comfortable option for horses prone to rubbing or pinching.
• Driving/harness horses: Full cheeks are traditional in driving because they help prevent the bit sliding through the mouth when direct rein contact isn't always available (as with long driving reins), and offer better steering cues without a rider's leg aids.
• Young horses in lunging or early ridden work: Often used with "bit keepers" (small loops connecting the upper cheek to the browband/headstall) specifically to reinforce the "give and take" steering response horses are taught early on.

Competition legality

The Full Cheek is FEI-approved, including for dressage, making it a permitted option at all levels of affiliated competition.

A note on safety

Full cheek bits carry a practical risk: the protruding cheek bars can catch on equipment, fencing, or other objects. For this reason, they're almost always used with bit keepers — small leather loops attaching the upper cheek to the bridle's cheekpiece — to keep the bars stable and reduce the chance of snagging.

Summary

The Full Cheek is valued for its steering/lateral assistance, mouth stability, and comfort, making it a popular, FEI-legal choice for young horses learning directional cues, horses needing extra straightness support, or driving horses — rather than for any leverage or "stronger" stopping power, since mechanically it functions as a direct-pressure snaffle.

This combines the classic single-hinge mouthpiece shape with a copper mouthpiece (either solid copper or copper-coated over a stainless core), pairing the clear, direct action of a single joint with copper's natural salivation-encouraging taste.

Design

• The mouthpiece consists of two bars joined by a single center hinge, producing the classic "nutcracker" fold under rein pressure — the same core structure as any single-jointed snaffle.
• Made of, or coated in, copper, a soft, warm metal with a naturally sweet taste that horses generally find pleasant.
• Copper is softer than stainless steel, so a solid copper mouthpiece is often made slightly thicker than an equivalent stainless steel one to compensate for wear and maintain strength, though thickness varies by manufacturer and design.

Function

• Nutcracker action, unchanged mechanically: As with any single joint, when rein pressure is applied, the two halves fold upward at the center hinge, putting pressure on the tongue, bars, and potentially the roof of the mouth (palate) — this fundamental action is the same regardless of material.
• Encourages salivation and acceptance: Copper's taste stimulates saliva production, helping keep the horse's mouth moist, encouraging chewing and mouthing of the bit, and generally promoting relaxation and a softer jaw — this is copper's primary functional benefit over stainless steel.
• Warmer, more palatable feel: Copper offers a warmer, more inviting sensation than stainless steel, which some horses accept more readily from the outset.
• Direct, clear signal: As with any single joint, there's no additional link or plate diffusing the pressure — the rider's cue remains straightforward and unambiguous, now paired with a material that encourages a relaxed, accepting mouth rather than tension or resistance.
• No leverage or added severity: As with any single-jointed snaffle, this works purely on direct pressure, with no shank or curb chain.

What it's good for

• Young horses starting bit training: Frequently recommended specifically as a "nice training bit" to help young horses establish balance, learn to bend, and become accustomed to contact, since the copper encourages a relaxed, accepting mouth from early exposure.
• Horses that need encouragement to relax and salivate: Particularly useful for tense, dry-mouthed, or resistant horses that benefit from copper's taste-driven stimulation, more so than a plain stainless mouthpiece would offer.
• Nervous or anxious horses: Copper's calming, salivation-promoting effect is often specifically noted as helpful for horses that are nervous or tense in the mouth.
• Riders wanting simple, direct communication with a taste-based acceptance boost: Suited to horses that respond well to the clarity of a single joint, but would benefit from copper's encouragement toward a soft, relaxed mouth.
• Teaching suppleness and lateral work: The independent movement of each side, combined with clear pressure, makes this a reasonable choice for early suppling and bending exercises.

A note on severity and wear

• The nutcracker action itself is unchanged by material — copper doesn't soften the mechanical fold or reduce palate contact the way a double-jointed design would; its benefit is entirely about taste and salivation, not about lessening the single joint's inherent action.
• A thinner copper mouthpiece is generally considered more severe than a thicker one, so mouthpiece thickness is worth considering alongside the material itself.
• Copper is a softer metal than stainless steel and can wear or show tooth marks over time, particularly with horses that chew persistently, so periodic inspection is worthwhile.

A note on classification

• The overall lateral action still depends on the cheek style (loose-ring, D-ring, eggbutt, Full Cheek, etc.) this mouthpiece is built into.
• This is generally considered a standard, moderate mouthpiece mechanically (same nutcracker action as any single joint), with copper adding a specific taste- and acceptance-focused benefit rather than reducing the bit's underlying severity.

Summary

A Single-Jointed Copper bit keeps the classic, direct nutcracker action of a single-hinge mouthpiece, while copper's natural sweet taste encourages salivation, relaxation, and acceptance — making it a popular choice for young horses starting bit training, nervous or tense horses, and any horse that benefits from a taste-driven nudge toward a soft, accepting mouth, though the mechanical action itself remains the same as any single-jointed snaffle.
