How to Use a Tom Thumb Bit

The Tom Thumb bit is a good choice for both young horses and older ones, and it is one of the most widely used bits for Western style riding. The Tom Thumb is jointed like a snaffle, but unlike a plain snaffle, this bit has a shank and a curb chain to provide additional leverage. But in order to be effective, the Tom Thumb must be used properly.

      Attach the reins to the rings at the bottom of the shank on the Tom Thumb bit. Place the bridle on the horse and tighten the curb chain. When the curb chain is properly set, you will be able to get two or three fingers between the curb chain the horse's chin.
