The tom thumb bit offers more precision and control due to the lifting effect in front which can assist the rider in helping to sit the horse back on its hocks, combined with poll pressure from the leverage action. Can be used with one rein on either the snaffle ring or the lower ring or with two reins.
The brass alloy roller link in the centre of this bit can help to calm and focus horses as well as aid salivation. The mouthpiece also has copper inlay strips on one side.
In good used condition with oxidisation as you would expect from a sweet iron bit.
