Horse Western Tom Thumb Bit | Brass Single Joint Mouthpiece & Swept Shanks | BI-0040

BI-0040 Premium Western Tom Thumb Bit with Brass Single Joint Mouthpiece

The BI-0040 is a refined western Tom Thumb curb bit combining a warm gold brass single-jointed mouthpiece with polished stainless steel swept shanks. The brass mouthpiece encourages salivation and a relaxed, accepting jaw — making this a more horse-friendly alternative to a standard stainless steel Tom Thumb — while the swept shank geometry provides a progressive, slightly delayed leverage action that rewards horses responding to light rein cues.

Key Features

• Gold brass single-jointed mouthpiece — the warm brass alloy encourages salivation and a softer, more accepting contact; the single joint creates a V-shape action on the bars, tongue, and corners for a clear, responsive rein signal
• Swept shank design — the curved shank geometry creates a slightly progressive leverage action compared to straight shanks, giving the horse a moment to respond before full poll and curb pressure engages
• Small upper headstall rings — for clean, secure headstall attachment
• Lower rein rings — for precise rein attachment at the base of the shank
• Stainless steel & brass construction — rust-resistant shanks with a warm brass mouthpiece; durable, hygienic, and easy to maintain

How to Use

Always use with a properly fitted curb strap or chain. The brass mouthpiece and swept shanks make this an excellent transitional bit for horses moving from a snaffle into neck reining and collection work. The brass encourages salivation from the moment the bit is fitted — use with light, educated hands for best results.

Ideal For

Horses transitioning from a snaffle to a leverage bit, western pleasure horses, trail horses, and any horse that benefits from a salivation-encouraging brass mouthpiece with a mild, progressive leverage action. A popular everyday western bit for riders who want performance and comfort in one package.

Size Guide: Measure your horse's mouth width from corner to corner and add 0.5 cm for the ideal fit.
