Stainless Steel 5" HBT Shank with Sweet Iron Comfort Snaffle Wide Barrel (MB 02, Level 1) Copper Inlay. This mouthpiece is made of polished Sweet Iron which naturally oxidizes or rusts. Harmless to horses, it has a sweet taste and promotes salivation.
The curve makes more room for the horses tongue under the bit. The barrel in the center is the same width as the center piece on a traditional three-piece mouthpiece so applies approximately the same pressure on the tongue. However, the barrel distributes the pressure more kindly than the traditional centerpiece and creates the Independent Side Movement .
