Bit has 2 mouthpieces, each one single jointed and made of twisted wire.
Action: The two joints amplify the nutcracker action. The wire makes the mouthpieces thin and sharp. The two mouthpieces cause extreme pressure on the bars. This bit is very severe, and should only be used by skilled riders with soft hands. Some people do not use these bits because they believe them to be cruel.
Uses: Not permitted for dressage. Very severe, used on horses that are very strong.
