The full cheek has straight cheek pieces, with a solid ring to attach to the rein. Because of this shape more pressure is gained on the cheeks of the horse. This makes a horse easier to turn and the bit cannot be pulled through the mouth so easily. In addition, this bit lies calm and stable in the mouth. The full cheek is an ideal bit for young or very hot horses who may not understand steering. The straight pieces on the cheekpiece are slightly bent outwards so that they cannot come into contact with the side of the horse's head. It is important that you put the bit in the mouth with the straight pieces facing outwards so that they can't cause wounds. The locked mouthpiece resembles a jointed mouthpiece but cannot fold as much as a jointed bit. When pressure is applied on the reins, the bit locks, transforming it into a straight bar and making it a sharper bit. With less pressure on the reins, the bit changes back into a jointed bit. This makes it an ideal bit for horses that are against the hand.
