From the manufacturer: Got a problem horse? This bit is worth looking at.
This bit may look like a strong bit, but if used with a snug curb, the sweet iron mouthpiece will continue to lay flat across the horse's mouth and bars. The Rutledge has been used quite successfully with horses that have split or damaged tongues and bars, or plain anxious about their mouths. The shank is flat and allows the curb to move from side to side, which is a new sensation for most horses. Horses seem to go progressively better within only a few days as they become accustomed to this new action.

Many top ropers and barrel racers have reported tremendous results and satisfaction using the Rutledge roper on HARD TO STOP horses. The revolving mouthpiece stays in place and lets you pull the curb chain against your horse's chin for a new feeling to your horse. This is not a severe bit, yet very effective and human and may be used as an all-around using bit.
