One of the most popular curb bits. Very good low leverage bit for horses with a good mouth. Solid cheeks for stability and a medium port with a good deal of tongue relief. Sweet iron naturally rusts into a light patina. The rust creates a sweet taste for the horse, making the bit more acceptable and increasing salivation for a supple mouth. Cheeks curve backward, but not as much as on the 651 Reinsman "C" Bit. A popular choice among cutters, reiners and trail riders.
