One of the most basic shanked type snaffle bits, the Tough-1 Tom Thumb Bit with Copper Mouth for Miniature Horse serves as an excellent transition bit form a ring snaffle to a longer shanked snaffle or to a curb bit. This bit uses a small amount of curb pressure or leverage. The bit's loose cheeks move independently allowing for more lateral flexibility. This is a great bit in a hard to find size.
