Shires Western Tom Thumb Horse Bit - Copper Mouthpiece & Stainless Steel Shanks

Refine Your Cues with the Shires Western Tom Thumb

Moving your horse from a snaffle to a curb can feel like a big leap, but the Shires Western Tom Thumb With Copper S/Steel is designed to make that transition seamless. Whether you’re looking to lighten up a horse that’s getting heavy in the hand or you are ready to start neck reining, this bit offers the perfect balance of leverage and familiarity.

Built with a focus on clear communication, this bit combines the classic single-jointed action your horse already knows with short, stainless steel shanks for gentle poll pressure. It is a reliable choice for the ranch or the trail, ensuring your horse stays responsive without the harshness of longer-shanked bits.

Why We Love the Shires Tom Thumb

• Encourages a Softer Mouth via the full copper joint, which promotes salivation and keeps your horse relaxed and "mouthing" the bit during your ride.
• Gentle Leverage Action provided by the short, straight stainless steel shanks, offering just enough poll pressure to refine your cues without being aggressive.
• Familiar Nutcracker Effect through the single-jointed mouthpiece that applies traditional pressure to the bars and tongue, making it an ideal "bridge" bit for training.
• Durable, Low-Maintenance Design featuring high-quality stainless steel that resists rust and corrosion, ensuring it stands up to the rigors of daily barn life.
• Improved Front-End Lift for horses that tend to lean on the bit, helping them respond to poll pressure and carry themselves with more balance and collection.

Best For

Transitioning riders and Western pleasure enthusiasts looking for a mild leverage bit to move from two-handed snaffle riding to refined, one-handed cues.

Frequently Asked Questions

Q: What size should I choose for my horse?

The Shires Western Tom Thumb comes in 5" (standard) and 5.5" (large) widths. We recommend measuring your horse's current bit or using a bit sizer, ensuring you leave about 1/8" to 1/4" of space on each side to prevent the shanks from pinching the lips.

Q: Is this bit considered a snaffle or a curb?

While it has a jointed mouthpiece like a snaffle, the addition of shanks makes the Shires Western Tom Thumb With Copper S/Steel a leverage bit (curb). It is often called a "transition bit" because it uses both mouth and poll pressure to communicate.

Q: How high should the bit sit in the horse's mouth?

For a proper fit, adjust your headstall so the bit sits at a height that creates one to two small wrinkles at the corners of the horse's mouth. This ensures the bit is stable and effective without causing discomfort or rubbing.
