One of the most basic shanked type snaffle bits, the Tomb Thumb snaffle 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 loose cheeks move independently allowing for more lateral flexibility. This is a nice bit and our last one. The company we got this from is no longer in business. Stainless Steel, 4 3/4" mouth
