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.
The action works on nose, corner of the mouth and curb for more complete control of your horse's head position. Three pressure point action helps to prevent lessening of response over time so that the bit action remains "fresh", even over long term use.
