what is the difference between a curb and a snaffle bit?
Differences Between Curb and Snaffle Bits. Curb and snaffles are two styles of horse bits that each have their own uses. Snaffle bits are mild, simple round-cheeked bits, while curb bits are harsher and normally have metal shanks coming down from the cheekpieces. Choosing the right bit can make a big difference in how your horse performs for you when you ride.
A snaffle is one type of bit. There are three main types, snaffle, curb and hackamore. A hackamore has no mouthpiece (bitless bridle). A curb has shanks, and a snaffle does not. For a snaffle, the reins are right at the corners of the horse's mouth.
