Mullen Square Twist
The Mullen is a strong bit which creates direct pressure on the tongue. Used for a strong older horse and will also bring the head down.
The Square Twist will create more pressure points on the mouthpiece which will make it stronger than the Round Twist and Smooth.
The Mullen Square Twist applies pressure across the tongue and bars. Pressure applied to the tongue is direct and constant. The Mullen Square Twist has been shaped to fit the curve of the horses mouth, this curve also allows pressure to be spread over a large surface area. The square twist is a stronger specialization than the round twist as the spines are a smaller, sharper surface area. This specialization does apply a great amount of pressure on the tongue and bars as each curve creates an individual pressure point where it lands. Due to the mouthpiece being a solid, there will be no squeeze on the bars. The Mullen is available in Sweet Iron. The Sweet Iron material was chosen as a metal option as it oxidizes. Oxidization encourages salivation and acceptance of the mouthpiece. The Mullen Square Twist is not flexible.
