BEST SWEET IRON MOUTHPIECE

Myler MB 36 Western Curb with Sweet Iron

Myler

The Myler MB 36 Western Curb with Sweet Iron stands out as best-in-class for horses that require a mouthpiece engineered to encourage salivation and softer contact; the sweet iron encourages acceptance while the MB mouthpiece geometry reduces tongue pressure. Technically more anatomical than the Reinsman and smoother in corrective action than the Classic Equine, it typically costs more up-front but can shorten training time and improve responsiveness, producing long-term value for serious trainers.

BEST ANTIQUE TOM THUMB STYLE

Metalab Antique Tom Thumb Snaffle Curb Bit

Metalab

The Metalab Antique Tom Thumb Snaffle Curb Bit occupies a niche in the collection by honoring traditional styling and providing hybrid snaffle/curb action for riders seeking period-correct appearance with light leverage. Technically simpler and often more affordable than modern competition bits, it is less specialized for high-level reining than the Reinsman or Myler but offers strong aesthetic and historical value for collectors and showmen emphasizing classic Western presentation.

What Research and Expert Guidelines Say About Curb Bit Function

Scientific studies and equine science guidance focus less on brand names and more on biomechanics: how bit shape, mouthpiece material and shank length change pressure distribution across the bars, tongue and poll, and how that affects head carriage and responsiveness. Research and veterinary guidance emphasize that correct fit, consistent rider hands and progressive training have more impact on welfare and performance than any single bit type. At the same time, controlled studies and field trials show measurable differences in horse responses to materials like sweet iron versus stainless steel, and to ported versus straight mouthpieces.

Sweet iron and some carbon steel mouthpieces tend to encourage salivation and a softer mouth in short-term trials, which can increase acceptance of the bit.

Higher or shaped ports reduce direct tongue pressure but increase leverage on the poll and bars if paired with long shanks; balance of port height and shank length matters.

Longer shanks increase mechanical advantage and poll pressure for the same rein force; this can improve stop and rollback cues in trained horses but requires a light, experienced hand.

Studies of rein tension and rider input show that bit choice alters how much rein force is needed for a cue, but rider consistency and skill remain the primary determinant of rein tension patterns.

Proper curb chain adjustment and mouthpiece fit reduce localized pinching and distribute pressure more evenly, lowering the risk of discomfort-related resistance behaviors.

Across Canada this selection meets the needs of ranchers, reining and cutting competitors, and trail riders who require reliable, discipline-specific curb bits. The Reinsman Pro Reiner 7 Shank Curb Bit offers traditional leverage for strong reining cues; the Myler MB 36 Western Curb with Sweet Iron provides a responsive, salivation-promoting mouthpiece well suited to varied conditions and is our top overall pick for 2025; the Classic Equine Goostree Medium Port Correction Bit gives targeted correction for schooling; the Professionals Choice Bob Avila Cathedral Port Curb blends a forgiving port design with competition-friendly control; and the Metalab Antique Tom Thumb Snaffle Curb Bit brings a classic profile for riders who prefer a time-tested feel. I hope you found what you were looking for — if not, refine or expand your search using the site search to filter by shank length, mouthpiece material, port height or intended discipline.
