Eggbutt from Bombers.

Eggbutt prevents the horse from being pinched in the lips/corners of the mouth by the bit rings and provides a stable feeling against the horse. It also prevents the bit from sliding through the mouth. The release is somewhat slower and it also applies a little pressure on the neck.A horse that shakes its head or sticks out its tongue are classic signs that the horse has a sensitive tongue. The McHardy mouthpiece was developed with this in mind. McHardy has a medium-high port that provides space for the tongue and reduces pressure on the tongue, and a roller in the middle that increases pressure on the bars.
