This is a nice Tom Thumb bit made of Stainless Steel. Cheeks measure 5" and the shanks measure 3". Available in 3 1/2" - 3 3/4" and 4". 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. A great bit in a hard to find size. This cute little bit is made much smaller to fit the little guys.
