This is a slightly different version of the famous "Million Dollar Bit" or SS Combo.
The shanks are a shorter tear drop about 5" whereas the Million Dollar bit is about 7 inch shank.
A stiffer type of bit that provides excellent handling qualities. The "stops" on the shanks minimize the sliding action and keep the mouthpiece in place. With a rope over the nose, this bit helps collect the horse and bring his face around.
