Eggbutt from Bombers.

Eggbutt prevents the horse from being pinched in the lips/corners of the mouth by the bit rings and provides a more stable feeling against the horse. Eggbutt ensures that the bit remains still in the horse's mouth.

Ported Barrel was created to reduce pressure on the tongue with the help of the medium-high port, which creates more space for the tongue. The pressure on the bars is reduced by distributing the pressure over a larger area and preventing the nutcracker effect.
