Slow Twist

 What it is: A mouthpiece (usually single-jointed) with a slight twist in the cannons. Thicker and with fewer twists than a wire bit, has fewer edges than a corkscrew.

Action: The twist causes edges that result as pressure points in the horse's mouth. Increases pressure on the tongue and bars, also acts on the lips. Generally considered strong and fairly severe.

Uses: Most commonly found on snaffles, quite rare on pelhams and gags. Usually seen in English disciplines. Not permitted in dressage competition.

Note: The slow twist is often incorrectly used to refer to the corkscrew or a wire bit. These bits are not the same
