Mackey Dr Bristol Eggbutt is made from from the highest grade of stainless steel, which is lost wax cast and hand polished. This mouthpiece has 2 joints in the centre, the link is longer and more rectangular in shape but flat, and it is set at a slight angle. The main objective of this bit is to apply pressure onto the tongue, and to the bars and lips of the mouth, encouraging the horse to stretch into contact. The double joint reduces the nutcracker effect found in single-jointed snaffles. The middle link is angled slightly in comparison to the side pieces of the bit, which means the thin edge of the rectangle presses into the tongue, thus applying the pressure. Each side of this bit is perfectly balanced which will assure total comfort and response. Comes in various sizes.
