Tom Thumb Curved Shanks Bit SS With Single Jointed Brass Mouth is a type of Western curb bit that closely resembles a snaffle bit but includes shanks to provide leverage, making it a hybrid between a snaffle and a curb bit. It is characterized by a single jointed mouthpiece and short shanks, which can offer more control than a typical snaffle but with potentially more direct pressure than other curb bits.

Single-Jointed Mouthpiece: The mouthpiece is similar to a snaffle with a single joint in the center, creating a nutcracker effect that applies pressure to the bars, tongue, and roof of the mouth.

Short Shanks: The shanks are relatively short, which means the bit provides leverage but to a lesser degree than bits with longer shanks. The shanks are often straight or slightly curved.
